Fig. 2. Mean concentrations of 25OHD, iPTH and 1,25(OH)2D across the menstrual cycle. Data are presented as means (±SE). The PMS group is represented by circles; the asymptomatic group by squares. EF denotes early follicular phase; LL denotes late luteal phase of the menstrual cycle. The asterisk indicates p<0.05 for the change from EF to Day 0 or from Day 0 to LL. 25OHD represents 25 hydroxyvitamin D; iPTH represents intact parathyroid hormone; 1,25(OH)2D represents 1,25 dihydroxyvitamin D. The asterisk indicates p<0.05 for controls vs. PMS. The double asterisk indicates p<0.01 for controls vs. PMS. The dagger refers to p<0.01 for the change from EF to Day 0.
