Figure 3. Pooled effect estimates on the differences in carotid-femoral pulse wave velocity (cf-PWV) (m/s) between living kidney donors and their respective healthy comparators. Because predonation values for Bahous et al⁹ and Kasiske et al¹³ were not provided, mean differences between living kidney donors and controls were calculated using their mean absolute cf-PWV values. In the study by Bahous et al, the number of living kidney donors allocated to each measurement was reduced by 50% to decrease ‘double-counting errors’ during the analysis. NRR, non-recipient related; RR, recipient related.
