  • Clinical markers of cardiovascular disease were measured in study animals after 4 hr of fasting at both 6 and 24 wk of age. Baseline measures are from 6-wk-old fasted mice fed a synthetic diet. Measures at 24 wk of age, after diet, include mice on both the low-fat, high protein diet and the high-fat, cholic acid diet; diet was used as a covariate in the analysis. The statistic reported is log of the odds ratio (LOD). QTL, quantitative trait loci; DO, Diversity Outbred; NA, not available.
