The mean percentage change in fasting blood glucose levels of experimental animals treated with the DCM leaf extract of Gnidia glauca for 6 weeks. Each point on the curve represents the mean of the replicate measurement n = 5 expressed as Mean ± S.D. The weekly percentage changes in fasting blood glucose levels among the studied groups with a similar lower-case letter (such as [c & cd] or [d & cd) are not significantly different from each other (p > 0.01). However, the weekly percentage changes in fasting blood glucose levels with different lower-case letters (such as a, bc & d) indicates statistical difference in means among the studied groups (p ≤ 0.01). Inferential statistics were performed using One way-ANOVA to test for statistical differences among studied groups. Tukey's post hoc test was then done for pairwise separation and comparison of means.
