Figure 2.

Relative levels of treatment, covariate, and individual effects on change in Physical Functioning scores. This figure illustrates the expected impact, in Physical Functioning points (adjusted for Physical Functioning level at T = 0 [6 months after randomization]), of study covariates as well as individual differences (expected difference between two “similar” men and the expected deviation from “similar” men). Individual differences pertain to systematic variation in Physical Functioning among patients sharing the same covariate profile (including receipt of finasteride). Effects on Physical Functioning are also shown at T = 6.5 (7 years after randomization). Covariates associated with a negative impact on Physical Functioning scores are preceded by a minus sign (−) and those associated with a positive impact on Physical Functioning scores are preceded by a plus sign (+).
