Table 2: Mean and standard deviation of 25(OH) D3 serum concentration for menand women in the clinical group. 34.3% women and 40.5% men had 25(OH)D3concentrations below 50 nmol/l. 61.7% women and 68.6% men had 25(OH)D3concentrations below 75 nmol/l. Women have a significantly higher mean 25(OH)D3 concentration (mean: 69.6 nmol/l) compared to men (mean: 62.4 nmol/l,P<0.00001).
