In patients with MGMT unmethylated glioblastoma, PFS (obese vs. non-obese: 8.1 (95% CI 6.0–11.3) vs. 9.0 (7.9–9.8) months, p = 0.23; Fig. 1a) and OS (obese vs. non-obese: 17.6 (14.7–20.8) vs. 17.1 (15.8–18.9) months, p = 0.26; Fig. 1b) did not differ between obese and non-obese patients (Fig. 1). The gene discussed is MGMT; the disease is glioblastoma.
