Values of n are for numbers of participants who completed biometric and wellness measures at all 3 time points. WPAI:GH A2 is the percent activity impairment due to health, WPAI:GH B2 is the percent impairment while working due to health, WPAI:GH C2 is the percent overall work impairment due to health, and WPAI:GH D is the percent work time missed due to health.
