Figure 7.

Meta-regression analyses, excluding the study of recurrent RCC among KTx recipients with a previous history of RCC prior to KTX, showed no significant correlations between the year of study and mortality of patients with RCC (p = 0.56). The solid line represents the weighted regression line based on variance-weighted least-squares. The inner and outer lines show the 95% confidence interval and prediction interval around the regression line. The circles indicate log event rates in each study.
