Impact of donor sex. Waterfall plots of OS (A) and EFS (B) differentials based on predictions for the validation set. The OS and EFS differentials are noted on the vertical axis, with a zone of indifference denoted by the dashed gray horizontal lines at ±0.01, and the percentile of benefit on the horizontal axis. Differentials for a male donor vs a female; recipient male (female) with a solid blue line (dotted red line): in the left panel, the percentage of those who benefit from a male vs female donor for recipient males (females) in blue (red).
