  • “Simple main effects further identified a significantly greater FMD in the vitamin D group compared to the placebo group at 16 weeks.”
  • “A Treatment × Time interaction (F1,41 = 66.5; p<0.001) was detected such that a robust increase in 25(OH)D was observed in the vitamin D group, whereas the placebo group exhibited a slight increase in 25(OH)D.”
