Fig. 4: Overall survival (OS) according to histological subtype.

A OS by pS6 status; epithelioid patients. B OS by pS6 status; non-epithelioid patients. Interaction p-value (from Cox model including pS6 status with histology interaction): <0.001. Overall median OS was 23.1 months (95% CI: 19.9–25.2) for epithelioid patients and 13.7 months (95% CI: 10.7–15.7) for non-epithelioid. Log-rank p-value comparing pS6 high vs. low: 0.88 for epithelioid; <0.001 for non-epithelioid.
