From: Reduced body mass, food intake, and testis size in response to short photoperiod in adult F344 rats
Means (± SE) of body weight over 0 – 14 weeks (a) and 18–52 weeks (b), and means transformed to a percentage of the LD mean value over 0 – 14 weeks (c) and 18–52 weeks (d) in F344 rats in LD, INT, or SD. Standard error bars are not shown for data points in which error bars were smaller than the symbols. 'a' indicates a significant difference between the SD and LD groups at P < 0.05, and 'b' indicates a significant difference between the INT and LD groups at P < 0.05.
