Design outcomes

Primary

Measure	Time frame	Description
Bone Mass in Liver Transplant Patients	through study completion, an average of 4 years	Evaluation of bone mass in patients undergoing liver transplantation followed at the Endocrinology Operating Unit for Bone Mineral Metabolism, through the creation of a structured data collection in which to census all cases diagnosed and evaluated since 1/1/2009 at the U.O. Endocrinology of the S. Orsola-Malpighi Polyclinic. For the prospective phase, the expected duration of individual patient observation is 5 years
Calcium Metabolism Indices in Liver Transplant Patients	through study completion, an average of 4 years	Evaluation of laboratory values related to calcium metabolism in patients undergoing liver transplantation, specifically focusing on blood levels of calcium, phosphate, parathyroid hormone (PTH), and vitamin D. These parameters will be assessed using standard laboratory tests conducted at the Endocrinology Operating Unit for Bone Mineral Metabolism. Data will be collected through a structured registry that includes all cases diagnosed and evaluated since 1/1/2009 at the U.O. Endocrinology of the S. Orsola-Malpighi Polyclinic.
Fracture Incidence in Liver Transplant Patients	through study completion, an average of 4 years	Evaluation of fracture incidence in patients undergoing liver transplantation in patients undergoing liver transplantation followed at the Endocrinology Operating Unit for Bone Mineral Metabolism, through the creation of a structured data collection in which to census all cases diagnosed and evaluated since 1/1/2009 at the U.O. Endocrinology of the S. Orsola-Malpighi Polyclinic. For the prospective phase, the expected duration of individual patient observation is 5 years

Secondary

Measure	Time frame	Description
Prevalence of Fractures in Patients Undergoing Liver Transplantation	through study completion, an average of 4 years	This measure will assess the correlation between liver transplantation and the prevalence of fractures in patients followed at the Endocrinology Unit. Fractures will be identified through clinical records and radiological assessments. The prevalence will be reported as the percentage of patients with fractures (%) within the study population.
Relationship Between Biochemical Parameters and Bone Mineral Density (BMD) Trends in Liver Transplant Patients	through study completion, an average of 4 years	This measure will evaluate the correlation between specific biochemical parameters (e.g., calcium concentration in mg/dL, phosphate concentration in mg/dL, parathyroid hormone levels in pg/mL) and trends in bone mineral density (BMD) values in liver transplant patients. Bone Mineral Density (BMD) will be assessed using dual-energy X-ray absorptiometry (DEXA) scans, reported in g/cm². Biochemical parameters will be measured through blood tests, with each parameter reported in its respective unit of measure, with distinct units of measure and measurement tools explicitly identified.
