a nonsignificant trendP = .099
Compared with patients with a BMI ≥ 30, patients with a BMI < 25 had lower odds of achieving a PSA50 response (odds ratio [OR] = 0.28, 95% confidence interval [CI], 0.10-0.78, P = .015), and patients with a BMI of 25 to <30 demonstrated a nonsignificant trend toward lower odds of a PSA50 response (OR = 0.45, 95% CI, 0.17-1.16, P = .099).
