From: Levels of awakening salivary CgA in response to stress in healthy subjects
Levels of salivary chromogranin A (CgA) at awakening (7:00 a.m.) and at three time-points after awakening (7:30, 8:00, 8:30 a.m.) in high scorers and low scorers on the GHQ-28 “severe depression” subscale. Values are given as the mean ± standard error of the mean. *Significantly different from the high-scoring group (p < 0.05; Student’s t test), †significantly different from the CgA level at 7:00 a.m. in the low-scoring group (p < 0.05; analysis of variance and Bonferroni’s test)
