Features of survival analysis on patients on the «waiting list» for kidney transplantation
Published 2019-08-01“…Since competing events are censored, it is impossible to directly assess the impact of covariates on their frequency, because there is no direct relationship between the regression coefficients and the intensity of these events. The determination of the median waiting time on the basis of such analysis generates a selection bias, which inevitably leads to a biased assessment. …”
