Mean (95% CI) for baseline and LOCF values at 1, 3 and 6 months.
1
Change from baseline to LOCF is statistically significant at 6 months within group p<0.05
2
Analysis of variance (ANOVA) for LOCF at 6 months between groups adjusted for baseline levels of each parameter, change in physical activity over 6 months and day of menstrual cycle.
IER = intermittent energy restriction, CER = continuous energy restriction.
Baseline 53 IER and 54 CER, 1 month 51 IER and 51 CER, 3 months 45 IER and 47 CER, 6 months 42 IER and 47 CER.
