Table 3.

Selected parameters at baseline and follow-up in study participants with available values at both study visits.

	Baseline	Follow-Up	Treatment Effect	p-Value
IGF-1 (ng/mL)
Vitamin D (n = 86)	113.4 ± 38.2	116.9 ± 33.3	3.1 (−5.6 to 11.9)	0.48
Placebo (n = 89)	122.5 ± 45.2	120.0 ± 47.6	3.1 (−5.6 to 11.9)	0.48
1,25(OH)₂D (pg/mL)
Vitamin D (n = 85)	52.1 ± 18.6	60.0 ± 22.2	9.2 (4.4 to 13.9)	<0.001
Placebo (n = 86)	49.0 ± 19.3	48.7 ± 16.6	9.2 (4.4 to 13.9)	<0.001

Data are shown as means with standard deviation. Treatment effects with 95% confidence interval and p-values were calculated by ANCOVA for group differences at follow-up with adjustment for baseline values.
