The glucose tolerance and fasting insulin in PD vs PD.SHR4 congenic strains. The course of glycemic curves in PD (white squares) vs PD.SHR4a (black squares) and PD.SHR4b (gray triangles) male rats fed standard diet. Fasting insulin concentrations in PD (white bar) vs PD.SHR4a (black bar) and PD.SHR4b (gray bar). Significance levels for oral glucose-tolerance test are given for the factor strain of one-way ANOVA; for fasting insulin, the strain comparison using the post-hoc Tukey’s honest significance difference test of the one-way ANOVA with strain as major factor is shown as follows: *P<0.05; **P<0.01; ***P<0.001.
