Does a restricted energy low glycemic index diet have a different effect on overweight women with or without polycystic ovary syndrome?

Values are mean ± SE, The Generalized estimation equation (GEE) method was used to compare the mean values at three study time points (baseline, 12th week and at 24 weeks) and between PCOS and controls
PCOS Polycystic ovary syndrome, Kcal Kilocalories, GI Glycemic index, GL Glycemic load
*Mann-Whitney U test was used to compare baseline variables between PCOS and controls
