Treatment effect assessed by different calculations of log PSA slopes after 6-month intervention

Slope of log PSA (n)Placebo (n)Sulforaphane (n)d (95% CI) in log (ng/mL)/moP
M0–M1–M3–M6 (n = 78)0.0421 (40)0.0248 (38)−0.0162 (−0.0374 to +0.0031)0.11
M0–M1–M3–M6 (n = 75)0.0447 (39)0.0240 (36)−0.0166 (−0.0382 to +0.0022)0.09
M0–M3–M6 (n = 75)0.0417 (39)0.0217 (36)−0.0180 (−0.0380 to −0.0007)0.044
M0–M6 (n = 75)0.0426 (39)0.0216 (36)−0.0180 (−0.0381 to −0.0004)0.04

NOTE: Results for each group are medians of the log PSA slope adjusted to the preintervention slope. The treatment effect (d) and its 95% CI are estimated according to Hodges–Lehmann.
