Figure 3. — Survival in the oropharyngeal squamous carcinoma chemoradiation (OPSC-CR) cohort stratified by estrogen receptor alpha (ERα) status. Kaplan-Meier plots stratified by ERα status for the OPSC-CR cohort are shown for (A) overall survival (OS, n = 215), (B) disease-specific survival (DSS, n = 215), (C) progression-free survival (PFS, n = 208), and (D) relapse-free survival (RFS, n = 194). Dashed lines represent ERα-negative patients, and solid lines represent ERα-positive patients. Hashes represent censoring times.
