Tukey’s Least Significant Difference (LSD) post-hoc analyses were performed ABT 263 when a significant interaction was observed to determine where JPH203 ic50 significance was obtained. Power calculations on changes observed in WOMAC scores indicated that an n-size of 8-10 per group would yield sufficient power (> 0.8) values. Additionally, power calculations on weight loss changes previously observed in similar studies indicated that a sample size of 10-15 per group yielded moderate to high power (> 0.8) values [20–22]. Results A total of 30 participants completed
the study (54 ± 9 yrs, 163 ± 6 cm, 88.6 ± 13 kg, 46.1 ± 3% fat, 33.3 ± 5 kg/m2). Of these, 16 participants in the GCM group completed the study (52 ± 10 yrs, 164 ± 7 cm, 89.7 ± 13 kg, 45.9 ± 3% fat, 33.3 ± 4 kg/m2) while 14 participants in the P group completed
the study (57 ± 7 yrs, 162 ± 6 cm, 87.3 ± 14 kg, 46.4 ± 4% fat, 33.2 ± 5 kg/m2). No significant differences were observed between groups on baseline demographic data. Energy intake Table 1 presents dietary intake data observed for the diet and supplement groups. The diet intervention significantly reduced energy intake in both groups over time.
