Figure 4

Patients with low vitamin D levels receiving vitamin D supplement for 3 months. (a) Successful vitamin D supplement, 25(OH)D concentration increased significantly after 3 months. (b) ACT scores were of significant differences among uncontrolled asthma group to compare between at baseline (, black) and after 3 months (, clear) of vitamin D2 supplement. (c) % predicted PEFR with partly controlled (, black) and uncontrolled asthma (, clear). % change ACT score (d) and % change percent predicted PEFR (e) compared between partly controlled and uncontrolled asthma group. The data were analyzed by Wilcoxon matched-pairs signed test and Mann–Whitney test. , , and .
