Adjusted estimates of physical performance mean values [mean (SE)] by serum 25-hydroxyvitamin D (25OHD) in men: the Pro.V.A Study.

<p>Notes: Adjusted mean values were obtained using the GLM procedure. Model 1 was adjusted for confounder variables (age, BMI, smoking habit, regular physical activity, season, depression, cognitive status, glomerular filtration rate (according to the MDRD formula). Model 2 was adjusted for the variables in Model 1 plus the covariates cardiovascular diseases, osteoarticular disease, COPD, and visual impairment;</p><p>SE =  standard error.</p
