almost significantp = 0.051
The correlation analysis for clock gene versus AANAT (output) revealed: 1) a significant (positive) correlation for Per1 and AANAT at CT15 (R 2 = 0.51, p = 0.036) and an almost significant correlation at CT21 (R 2 = 0.60, p = 0.051), 2) a positive correlation between Per2 and AANAT at CT15 (R 2 = 0.51, p = 0.035), but not at CT21 (R 2 = 0.45, p = 0.16), 3) and a positive correlation between Per3 and AANAT at CT21 (R 2 = 0.62, p = 0.037) but not at CT15 (R 2 = 0.31, p = 0.22).
