Table 2 Geometric mean values (GSE) of saliva cortisol in groups at different time points with p-values for the comparison with the low strain group and p-values for the comparison of the geometric mean change between different time points in the low strain group compared to the other groups. All women and men respectively.

From: The demand control model and circadian saliva cortisol variations in a Swedish population based sample (The PART study)

  Job strain Geometric mean values (GSE) in job strain groups at the different time points with p-values for the comparison between the low strain group P-values (< 0.10) indicating significant differences in mean change between different time points Ref = Low strain
