Figure 2: (a) Comparison of effect of vitamin D ≤20 nmol/l on lung function among groups. (b) Comparison of effect of vitamin D 21–50 (nmol/l) on lung function in groups. (c) Comparison of effect of vitamin D ≥51 (nmol/l) on lung function in groups. Group 1 = Vitamin D <21 nmol/l, Group 2 = Vitamin D >21–50 nmol/l, Group 3 = Vitamin D >50 nmol/l
