Model-based estimated mean secondary outcomes over time. Linear mixed-effects models adjusted for time, group, sex, ethnicity, baseline age, baseline BMI, and baseline maximum pain for 50-ft speed walk, Borg Perceived Effort, Patient-Specific Functional Scale, and Symbol–Digit Modalities Test. Model adjusted for time, group, time × group, sex, ethnicity, baseline age, baseline body mass index, and baseline maximum pain for 6-min walk. Model adjusted for time, group, time × group, sex, survey language, baseline age, baseline BMI, and baseline maximum pain for 12-Item Short-Form Physical Component Summary (SF-12 PCS). Vertical lines indicate 95% confidence intervals. Figure 3.1 6-Min walk. Figure 3.2 Borg Perceived Effort. Figure 3.3 50-Ft speed walk. Figure 3.4 12-Item Short-Form Physical Component Summary.
