25(OH)D, 25-hydroxyvitamin D; RM GLM ANCOVA, repeated-measures general linear model ANCOVA.

Data are presented as mean ± standard error.

RM GLM ANCOVA, controlling for BMI at baseline, explored differences in mean 25(OH)D between groups in sufficient and insufficient participants.

GLM ANCOVA, controlling for BMI at baseline, explored differences in mean 25(OH)D between groups in sufficient and insufficient participants.

P < 0·05 was considered statistically significant.
