CES= Center for Epidemiologic Studies
a
Greater hazard reflects 1 SD increase night cortisol (.787 nmol/L, (ln))
b
Greater hazard reflects 1 SD smaller hourly decline in salivary cortisol (.049 nmol/L, (ln)).
c
Smaller hazard reflects 1 SD greater decline in salivary cortisol over course of the day (21.4%)
