Twenty-four months changes in plasma 25-hydroxyvitamin D concentrations following surgery. 25-Hydroxyvitamin D (25(OH)D) was measured in plasma samples obtained at 0 (before surgery), and 1, 6, and 24 months following Roux-en-y gastric bypass surgery as described in Methods and Procedures section. Open squares depicts non-Hispanic white women (n = 6) and open circles depicts non-Hispanic African-American women (n = 3), the thick line depicts the averages of total population (n = 10), the thin line depicts the cutoff for normal vitamin D status (≥75 nmol/l). *Significantly different from baseline value (P < 0.05); †significantly different from 1 month value (P < 0.05).
