a
AMH is natural log transformed and continuous.
b
Linear regression models were used to estimate associations between 25(OH)D and AMH.
The β estimates have been presented as a percent change.
c
Adjusted for age, age-squared, BMI, hormonal contraceptive use, smoking and exercise. Missing exercise, N=5. For 25(OH)D: <12, N=464; 12–<20, N=647; 20–<30 N=346; ≥30, N=131.
AMH, Antimullerian Hormone; 25(OH)D, 25-hydroxyvitamin D.
