Key: Vitamin D deficient: 25(OH)D: < 20 ng/ml, Vitamin D insufficient: 25(OH) D: 20-29 ng/ml, Optimal Vitamin D 25(OH) D: ≥ 30 ng/ml, Severe Vitamin D Deficiency: 25(OH) D: < 10 ng/ml, n number of patients in each category. All values expressed as n(%) unless otherwise stated. p-values of ≤ 0.05 were considered statistically significant
