Figure 2. Meta-analysis for the association of APOL1 risk alleles with death-censored allograft survival across the GOCAR and CTOT studies.
HR estimates of the number of APOL1 risk alleles associated with DCAL from the GOCAR and CTOT cohorts for all ancestries were included in a fixed-effect meta-analysis. The HRs and corresponding 95% CIs for individual studies and meta-analysis are presented as forest plots. The size of the squares shown for the individual studies is proportional to the sample size of each study.
