Time frame: Day 1

Population: All participants eligible for analyses were included. Number analyzed is the number of participants with data available for analyses for the specific category. Participants are repeated for multiple CRAB signs and cytogenic abnormalities. Percentages were rounded off.

Clinical variables include date of latest symptomatic relapse and/or refractory episode, ISS disease stage, CRAB signs, other clinical variables (plasmacytomas: medullary or extramedullary, diffuse osteopenia, fractures, neurological symptoms, infections, concomitant diseases like diabetes, neuropathy, chronic obstructive pulmonary disease (COPD), cardiovascular disease, liver failure, psychiatric and/or neurological disorders, any other secondary disorders, cytogenetic abnormalities, risk according to cytogenetic profile at relapse(standard:trisomies,t\[11;14\];t\[6;14\],intermediate:t\[4;14\],g\[1q\], high:d\[17p\],t\[14;16\],t\[14;20\],other), treatment started after latest symptomatic relapse and/or refractory episode.

Time frame: Day 1

Population: All participants eligible for analyses were included. Number analyzed is the number of participants with data available for analyses for the specific category. Participants are repeated across multiple categories. Percentages were rounded off.

Sociodemographic variables included age(in years), sex(male or female), body mass index(BMI), residence(rural or urban), educational level(illiterate,no studies(can only read/write),primary studies,secondary studies,higher studies), work status(unemployed,active employment,temporarily/ permanently disabled, retired, other), cohabitation(lives-alone,with relatives,alone with help from a caregiver), need for financial assistance (yes/no), degree of dependence(independent,dependent:grade I-requires help to perform activities of daily living \[ADL\] at least once a day,grade II-needs help to perform ADLs 2 or 3 times a day or grade III-needs help to perform ADLs several times a day), healthy habits (high\[jogging;climbing;cycling;swimming;sports;intensive work;moving \>20 kg loads\], moderate\[walking;dancing;domestic chores;sports with children,walking house pets;general construction work;moving \<20 kg loads\] physical activity or inactive, smoking habit (yes/no), alcohol use (yes/no).

Time frame: Day 1

Population: All participants eligible for analyses were included. Number analyzed is the number of participants with data available for analyses for the specific category. Percentages were rounded off.

The EORTC QLQ-C30 contains 30 items across 5 functional scales (physical, role, cognitive, emotional, and social), 9 symptom scales (fatigue, nausea and vomiting, pain, dyspnea, sleep disturbance, appetite loss, constipation, diarrhea, and financial difficulties) and a global health status/QOL scale. Most of the 30 items have 4 response levels (not at all, a little, quite a bit, and very much), with 2 questions relying on a 7-point numeric rating scale with a recall period of the previous week. Raw scores are converted into scale scores ranging from 0 to 100. For the functional scales and the global health status/QOL scale, higher scores represent better QOL; for the symptom scales, lower scores represent better QOL.

Time frame: Day 1

Population: All participants eligible for analyses were included. Overall number of participants analyzed are the participants with data available for analyses.

The EORTC QLQ-MY20 has 20 items across 4 independent subscales, 2 functional subscales (body image, future perspective), and 2 symptoms scales (disease symptoms, and side effects of treatment) with a recall period of previous week. Scores from each subscale were transformed from 0 to 100. For the functional scales, high scores represent improvement. For the symptom scales, higher scores represent worsening.

The EORTC QLQ-MY20 has 20 items across 4 independent subscales, 2 functional subscales (body image, future perspective), and 2 symptoms scales (disease symptoms, and side effects of treatment) with a recall period of previous week. Scores from each subscale were transformed from 0 to 100. For the functional scales, high scores represent improvement. For the symptom scales, higher scores represent worsening. Spanish Translated Version of EORTC Multiple Myeloma Module included 4 factors, each factor corresponds to questions related to the particular component of the scale. Factor I indicate symptoms. Factor II indicates future perspectives. Factor III indicate adverse effects of the treatment. Factor IV indicates adverse effects of the treatment and body image. Each of these factors were used for the clinical validity of the scale.
