Kaplan-Meier curves showing survival of PKD patients receiving RRT during the study period. Panel a shows unadjusted data, whereas Panel b shows data adjusted for median age (58 years old). Panel c shows unadjusted data (age) but censored at first transplantation, whereas Panel d shows adjusted data (age) censored at first transplantation. For all comparisons, the unadjusted and age-adjusted outcomes vary significantly over time (p < 0.001)
