Distant metastases-free curves for RN versus PN after OW. A Distant metastases-free curve for RN versus PN in G1 subset after OW (p = 0.788). B Distant metastases-free curve for RN versus PN in G2 subset after OW (p = 0.699). C Distant metastases-free curve for RN versus PN in G3 subset after OW (p < 0.05). D Distant metastases-free curve for RN versus PN in G4 subset after OW (p < 0.05). The shaded area denotes the 95% confidence interval for the predicted probability. OW = overlap weighting; PN = partial nephrectomy; RN = radical nephrectomy
