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)/mo | P |
|---|---|---|---|---|
| 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.
