Fig. 2From: Physical exercise at the workplace prevents deterioration of work ability among healthcare workers: cluster randomized controlled trialChange in work ability index (WAI) from baseline (0-wks) to follow-up (10-wks) with workplace exercise (WORK; full lines) and home-based exercise (HOME; dashed lines). Values are means (SE) adjusted for baseline values. **Denotes greater reductions in WAI with workplace exercise compared to home-based exercise (Post hoc test: p < 0.01)Back to article page
