a Cage: Centered Age; FatCat: Normal vs. Overweight/obese; SE: Standard Error. Statistical intent to treat analyses using all available data was performed using SAS software version 9.2. The level of significance was set at P < 0.05 for all tests. Time variable is for changes from T1 (beginning of study) to T3 (end of study).
