Study IDST000978
Study TitleMetabolomics biomarkers and the risk of overall mortality and ESRD in CKD: results from the Progredir Cohort.
Study Typeongoing cohort study
Study Summary454 CKD participants were originally recruited from the outpatient services from Hospital das Clinicas, Sao Paulo. Extensive baseline data and biobank were collected between 2012-2013 in the Clinical Research Center, Universitary Hospital, Sao Paulo. Participants are being actively followed for events of mortality, renal replacement therapy and CVD. Death certificates are obtained from State and National Registries. For the this uploaded data, events were determined up to May 2017 (median follow-up time of 3 y). Censoring data was considered as the last day of contact.

Study CommentsEvents are overall mortality, RRT, and a composite outcome of mortality and RRT. In addition, we also provided the variable for competitive data analysis (RRT considering the competing effect of death). Please see below for description of Study Design. Cox_mortality: death events (for Cox proportional hazard models) Cox_RRT: renal replacement therapy events (for Cox proportional hazard models) Cox_composite_deathRRT: death events AND renal replacement therapy events (for Cox proportional hazard models) Competitive_RRTvs death: death or renal replacement therapy events (for competitive risk analysis) Time_death: follow-up time for death events and censored-participants (for Cox models) Time_Cox_RRT: follow-up time for renal replacement therapy events and censored-participants (for Cox models) Time_composite_deathRRT: follow-up time for death AND renal replacement therapy and censored-participants (for Cox models) Time_competitive_TRSvsDeath: follow-up time for renal replacement therapy, death or censored-participants (for competitive analysis)
