The Intrauterine and Nursing Period Is a Window of Susceptibility for Development of Obesity and Intestinal Tumorigenesis by a High Fat Diet in Min/+ Mice as Adults
Table 2
Effects of exposure to a 45% fat diet during various periods of life on absolute liver weight (ALW), relative liver weight (RLW), absolute spleen weight (ASW), and relative spleen weight (RSW) in female and male wild-type mice terminated at 23 weeks of age (mean of individual mice in the group ± SD).

Relative liver weight (RLW) (%) = absolute liver weight (ALW)/body weight (BW) × 100, relative spleen weight (RSW) (%) = absolute spleen weight (ASW)/BW × 100. g = gram. Dietary treatment groups within each gender with similar letters are significantly different.
