Fig 2. Body weight variation throughout 4 days of paradoxical sleep deprivation.

Body weight change (g) of the C (n = 10), RT (n = 10), PSD96 (n = 10), RT/PSD96 (n = 10) groups during 4 days of PSD. The variation was calculated by the equation: current weight—previous weight. Repeated measure ANOVA followed by Duncan’s post hoc. The data are presented as the mean ± standard deviation, significance accepted: p ≤ 0.05. *—Different from the previous body weight in the same group; ^†—Different from the C group at the same time; ^‡—Different from the RT group at the same time; ^x—Different from the PSD96 group at the same time.
