Figure 3: Changes in postprandial plasma glucose (PPPG) level (mg/ dL) in groups A, B, and C. PPPG level (mean± SD) in Group A are 210.5 ± 8.5, 195.8 ± 9.3, 178.5 ± 9.1 at weeks 4, 8, 12 respectively; in Group B are 191.7 ± 9.9, 177.8 ± 11.2, 157.2 ± 10.9 at weeks 4,8, 12 respectively; in Group C are 173.2 ± 9.4, 156.9 ± 8.5, 135.7 ± 8.3 at weeks 4,8, 12 respectively. *P < 0.05Weeks 4, 8, and 12 versus week 0 in groups A, B, and C. Intergroup comparison of PPPG levels at weeks 4, 8, and 12: At weeks 4, 8, and 12 (^{#}P < 0.05Groups B, C vs. Group A), (^{##}P < 0.05Groups C vs. Group B.) Statistical test used was analysis of variance followed by Tukey's honestly significant difference test
