Notes:

-First two columns give survival probabilities for PA-PN matched cohorts; second two columns give survival probabilities for PA-RN matched cohorts.

-Survival probabilities generated from an Inverse Probability of Treatment-Weighted (IPTW) Cox model with a time-dependent treatment variable

-Results are essentially the same as those from primary analysis

-RCC, renal cell carcinoma; RSS, RCC-specific survival; OS, overall survival; PA, percutaneous ablation; PN, partial nephrectomy; RN, radical nephrectomy
