Survival analysis confirmed a highly significant difference between the two cohorts, with OM patients experiencing a substantially reduced risk of death (HR = 0.1974; 95% CI: 0.1095–0.3559; P < 0.0001 by log-rank test).

Patients in the OM group tended to be older than those in the PM group (median age: 67 versus 62 years, respectively), although this difference did not reach statistical significance ( P = 0.0724).
