| Plasma lipids (mg/dL) | |||
| Total cholesterol | 218.69 ± 4.5 | 214.95 ± 6.1 | NS |

Data are given as means ± SEM. All p-values were corrected for differences in age The statistical analysis of total triglycerides and plasma insulin were performed on log-trasformed values, but the untrasformed values are given in table. Continuous variables were compared by t-test and categorical variables by Χ2 test.
