The data mimic the PREDIALA study described and analyzed in Proust-Lima et al (2021 - https://arxiv.org/abs/2109.13064). The study aims to describe the trajectories of depressive symptomatology of patients suffering end-stage renal disease and registered on the renal transplant waiting list. Repeated measures of anxiety and depression (HADS) were simulated at different times of measurement for 561 subjects. Four time-independent covariates were also generated: group (dialyzed or pre-emptive), sex and age at entry in the cohort and time on the waiting list at entry in the cohort.
