Inclusion criteria

* Men or women at least 40 years old with a diagnosis of type 2 diabetes * Established cardiovascular disease, including at least 1 of the following: * Coronary artery disease (CAD) with any of the following: * Documented history of spontaneous myocardial infarction (MI) * ≥50% stenosis in 1 or more major coronary arteries, determined by invasive angiography * ≥50% stenosis in 2 or more major coronary arteries, determined by computed tomography coronary angiography (CTCA) * History of surgical or percutaneous coronary revascularization procedure * Cerebrovascular disease - any of the following: * Documented history of ischemic stroke * Carotid arterial disease with ≥50% stenosis, documented by carotid ultrasound, magnetic resonance imaging (MRI), or angiography * Carotid stenting or surgical revascularization * Peripheral arterial disease with either of the following: * Intermittent claudication and ankle-brachial index \<0.9 * Prior nontraumatic amputation or peripheral vascular procedure (eg, stenting or surgical revascularization), due to peripheral arterial ischemia * Note: Supporting medical documentation is required in all instances * HbA1c ≥7% (≥53 mmol/mol) and ≤10.5% (≤91.3 mmol/mol) based on central laboratory assessment at screening * Body mass index (BMI) ≥25 kg/m2 * At the time of signing the informed consent: Contraceptive use by men or women should be consistent with local regulations regarding the methods of contraception for those participating in clinical trials. * Male patients: Men, regardless of their fertility status, with nonpregnant women of childbearing potential (WOCBP) partners must agree to either remain abstinent (if this is their preferred and usual lifestyle) or use condoms, as well as 1 additional highly effective (less than 1% failure rate) method of contraception (such as combination oral contraceptives, implanted contraceptives, or intrauterine devices) or effective method of contraception (such as diaphragms with spermicide or cervical sponges) for the duration of the study and until their plasma concentrations are below the level that could result in a relevant potential exposure to a possible fetus, predicted to be 90 days following the last dose of study drug. * Men and their partners may choose to use a double-barrier method of contraception. (Barrier protection methods without concomitant use of a spermicide are not an effective or acceptable method of contraception. Thus, each barrier method must include use of a spermicide. It should be noted, however, that the use of male and female condoms as a double barrier method is not considered acceptable due to the high failure rate when these barrier methods are combined). * Periodic abstinence (eg, calendar, ovulation, symptothermal, or postovulation methods), declaration of abstinence just for the duration of a trial, and withdrawal are not acceptable methods of contraception. * Men with pregnant partners should use condoms during intercourse for the duration of the study and until the end of the estimated relevant potential exposure in WOCBP (90 days). Men should refrain from sperm donation for the duration of the study and until their plasma concentrations are below the level that could result in a relevant potential exposure to a possible fetus, predicted to be 90 days following the last dose of study drug. Men who are in exclusively same-sex relationships (as their preferred and usual lifestyle) are not required to use contraception. * Female patients: Women of childbearing potential who are abstinent (if this is complete abstinence, as their preferred and usual lifestyle) or in a same-sex relationship (as part of their preferred and usual lifestyle) must agree to either remain abstinent or stay in a same-sex relationship without sexual relationships with males. Periodic abstinence (eg, calendar, ovulation, symptothermal, or postovulation methods), declaration of abstinence just for the duration of a trial, and withdrawal are not acceptable methods of contraception. Otherwise, WOCBP participating must agree to use 2 forms of effective contraception, where at least 1 form is highly effective (less than 1% failure rate), for the entirety of the study. Contraception must continue following completion of study drug administration for the entirety of the study and for 30 days thereafter. * WOCBP participating must test negative for pregnancy prior to initiation of treatment as indicated by a negative serum pregnancy test at the screening visit followed by a negative urine pregnancy test within 24 hours prior to exposure. * Two forms of effective contraception, where at least 1 form is highly effective, (such as combination oral contraceptives, implanted contraceptives, or intrauterine devices) will be used. Effective contraception (such as male or female condoms with spermicide, diaphragms with spermicide, or cervical sponges) may be used as the second therapy. Barrier protection methods without concomitant use of a spermicide are not a reliable or acceptable method. Thus, each barrier method must include use of a spermicide (ie, condom with spermicide, diaphragm with spermicide, or female condom with spermicide). It should be noted that the use of male and female condoms as a double barrier method is not considered acceptable due to the high failure rate when these methods are combined. * Women not of childbearing potential may participate and include those who are: * infertile due to surgical sterilization (hysterectomy, bilateral oophorectomy, or tubal ligation), congenital anomaly such as mullerian agenesis, or * postmenopausal - defined as either: A woman at least 40 years of age with an intact uterus, not on hormone therapy, who has cessation of menses for at least 1 year without an alternative medical cause, AND a follicle-stimulating hormone \>40 mIU/mL; or ii. A woman 55 or older not on hormone therapy, who has had at least 12 months of spontaneous amenorrhea; or A woman at least 55 years of age with a diagnosis of menopause prior to starting hormone replacement therapy. * In the investigator's opinion, are well motivated, capable, and willing to: * learn how to self-inject treatment (tirzepatide or dulaglutide), as required for this protocol (visually impaired persons who are not able to perform the injections must have the assistance of a sighted individual trained to inject the study drug; persons with physical limitations who are not able to perform the injections must have the assistance of an individual trained to inject the study drug), * inject study drug weekly, * have a sufficient understanding of 1 of the provided languages of the country such that they will be able to complete the patient questionnaires, and * make themselves available for the duration of the study, and who will comply with the required study visits. * Capable of giving signed informed consent

Change From Baseline to 36 Months in Estimated Glomerular Filtration Rate (eGFR) in Patients With High or Very-high Risk Chronic Kidney Disease (CKD)Baseline, 36 MonthsChange from baseline in eGFR calculated as difference between value at 36 months and baseline value. Participants included in this analysis were classified as having high or very high risk of chronic kidney disease at baseline based on their kidney function (eGFR) and urine albumin-to-creatinine ratio (UACR). High risk included participants with eGFR 45 to less than 60 milliliters/minutes/1.73 square metres (mL/min/1.73 m²) and UACR greater than 30 mg/g, or eGFR 60 mL/min/1.73 m² or higher with UACR greater than 300 mg/g. Very high risk included participants with eGFR less than 45 mL/min/1.73 m² or severely increased UACR (greater than 300 mg/g). These criteria are associated with an increased risk of worsening kidney function. Least squares (LS) mean was calculated using analysis of covariance (ANCOVA) model for endpoint measures: Variable = Baseline + Treatment + Analysis Country + Baseline sodium-glucose cotransporter-2 (SGLT-2) Use Flag.
Change From Baseline to 36 Months in Hemoglobin A1c (HbA1c)Baseline, 36 MonthsHbA1c is the glycosylated fraction of hemoglobin A. HbA1c is measured primarily to identify average plasma glucose concentration over prolonged periods of time. Change in HbA1c from baseline up to 36 months during in-trial period were reported. In-trial observation period was defined as the period from date of randomization to the first of (both inclusive): date of follow-up visit, date when participant withdrew consent, date of last contact with participant (for participant lost to follow-up), and date of death. LS mean was calculated using ANCOVA model for endpoint measures: Variable = Baseline + Treatment + Analysis Country + Baseline SGLT-2i Use Flag (Type III sum of squares).
Percent Change From Baseline to 36 Months in Body WeightBaseline, 36 MonthsLS mean was calculated using ANCOVA model for endpoint measures: Variable = Baseline + Treatment + Analysis Country + Baseline SGLT-2i Use Flag (Type III sum of squares)
Percent Change From Baseline to 36 Months in Urinary Albumin to Creatinine Ratio (UACR)Baseline, 36 MonthsUrine samples were collected for the analysis of UACR. UACR (gram per kilograms \[g/kg\]) was calculated as urine albumin (gram per liter \[g/L\])/urine creatinine (kg/L). Percent change from baseline at 36 months was calculated as: \[(UACR at 36 months - baseline UACR) / baseline UACR\] × 100. LS mean was calculated using ANCOVA model for endpoint measures: log(Actual Measurement/Baseline) = log(Baseline) + Treatment + Analysis Country + Baseline SGLT-2i Use Flag (Type III sum of squares).
Percent Change From Baseline to 24 Months in Blood Lipids (Total Cholesterol (TC), Low-Density Lipoprotein Cholesterol (LDL-C), High-Density Lipoprotein Cholesterol (HDL-C), and Triglycerides (TG))Baseline, 24 MonthsBlood samples of participants who had fasted for 12 to 14 hours were collected for lipid profile (TC, LDL-C, HDL-C, TG) assessment. The lipid profile asesses the risk of heart disease. Percent change from baseline = 100\*(post-baseline assessment - baseline assessment)/baseline assessment. LS mean was calculated using ANCOVA model for endpoint measures: log(Actual Measurement/Baseline) = log(Baseline) + Treatment + Analysis Country + Baseline SGLT-2i Use Flag.
