Tabled values are Pearson correlations except for those with asterisks (^*), which are partial correlations controlling for age, in those cases where age was correlated with the melatonin measure at p<0.100, at least. Significant correlations (p<0.05, two-tailed) are highlighted in bold.

P₄, progesterone.
