Serum 25(OH)D distribution in participants with increasing number of cardio-metabolic risk factors (central obesity, diabetes, low HDL-cholesterol, hypertension, current smoker, past history of CVD). The bars represent median and boxes represent interquartile range of serum 25(OH)D (nmol/L), dots represent outliers; n = 24, 87, 127, 149, 118 across groups with 0, 1, 2, 3, 4+ cardio-metabolic risk factors, respectively; p < 0.001 for each category of cardiometabolic risk numbers compared to reference group of 0 risk factors.
