These values are partial n-sizes of data previously presented by Linden et al. [15], and serve to provide information regarding the phenotype of each group for convenience to the reader. All data are presented as mean ± SD (n = 10–16 rats per group), 95% confidence intervals (CI) are presented, and data with different superscript letters indicate between-treatment differences (p < 0.05)
O-CON OLETF rats consuming a control diet during weeks 20–32 and were not treadmill-trained, O-WD/SED OLETF rats consuming a Western diet during weeks 20–32 and were not treadmill-trained, O-WD/EX OLETF rats consuming a Western diet during weeks 20–32 and were treadmill-trained 5 days/week; HOMA-IR, homeostatic model assessment of insulin resistance
