Figure 1: Changes in triglycerides (TG), total cholesterol (TC), lowdensity lipoprotein cholesterol (LDLc) in type 2 diabetic patients received 1 g/ day (group 1), 2 g/day (group 2), and 3 g/day (group 3) of Nigella sativa for 12 weeks. The corresponding parameters in the 3 groups were compared using analysis of variance. Data are mean ± standard error of mean of the values as percentages of the corresponding baseline values, considering baseline values equal 100. (a) Significance of difference between groups 2 and 1 (P < 0.05), (b) significance of difference between groups 3 and 1 (P < 0.05), and (c) significance of difference between groups 2 and 3 (P < 0.05)
