- Results determined using logistic regression with those in the highest quintile serving as the referent group. Results are expressed as odds ratio (95 % confidence intervals) * p < 0.05. 25 (OH) D, 25-hydroxyvitamin D3; 1,25 (OH) 2D, 1,25 dihydroxyvitamin D3. Model 1, adjusted for age and centre; Model 2, adjusted for age, centre and physical performance (sit to stand time and time to walk 50 feet); Model 3, adjusted for age, centre, physical performance and comorbidities; Model 4, adjusted for age, centre, physical performance, comorbidities, body mass index and depression (the presence of depression was determined using Beck Depression Inventory with scores ≥10 indicating depression)
