Differences between quartiles (qrtl) of Δ-cortisol (logarithmic morning salivary cortisol – logarithmic evening salivary cortisol) were examined by GLM (general linear model), using quartile 1 as reference.

aModel 2 = age, leisure time physical activity, smoking, education, alkohol consumption, oral contraceptives, and estrogen replacements.
