Groups that started with 150 males and 150 females were weighed weekly. Mice were fed a diet containing 6% fat (LabDiet® 5K52 formulation). The figure above shows monthly weights. Boxes extend from the 25th to 75th percentile. The horizontal line in each box shows the median weight and + shows the mean weight. Whiskers extend to maximum and minimum weights. The table below shows the mean and one standard deviation at even-numbered ages.
