Cumulative mortality rates in RCC patients: cryoablation vs. thermal ablation pre- and post-PSM. This figure compared cumulative mortality rates for patients receiving cryoablation (CA) versus thermal ablation (TA) in renal cell carcinoma (RCC) treatment, both before (left panel) and after (right panel) propensity score matching (PSM). The X-axis indicates time in months, while the Y-axis shows the cumulative mortality rate. Statistical analysis indicates a significant difference in mortality rates post-PSM (p = 0.012) favoring CA, suggesting a survival benefit after accounting for confounding variables
