Flow-madiated brachial artery dilation

	Vitamin D (n=30)	Placebo (n= 15)	P-value
Median baseline brachial artery diameter, mm (IQR)	4.74 (4.30–5.00)	4.50 (3.83–5.00)	0.493
Median baseline FMD, % (IQR)	2.87 (1.55–4.78)	2.46(1.68–6.43)	0.819
Median 12-week follow-up brachial artery diameter, mm (IQR)	4.75(4.21–5.07)	4.61 (3.90–4.99)	0.199
Median 12 week follow-up FMD, % (IQR)	3.87 (2.18–4.71)	2.75(1.82–6.59)	0.766
Median absolute change in FMD, % (IQR)	0.55 (−1.05–2.13)	0.29 (−1.61–1.77)	0.748
Mean absolute change in FMD, % ±sd	0.53 ±2.99	0.56 ±3.65	NA^a

Mean difference was not tested for statistical significance given the non-normal distribution of the measurement.
