Results are presented as estimated marginal means and are given as mean (95% confidence interval) for n = 55 participants. A linear mixed model including acute and chronic mental stress and significant co-variables were applicable was used for analysis. Data on the effect of acute mental stress obtained using the same model for analysis are presented in Table 3. Statistically significant p values are indicated by an asterisk. The interaction of acute and chronic stress was not significant in any of the analyses and the p values are thus not reported separately. 1adjusted for Pittsburgh sleep quality index (PSQI), 2adjusted for International physical activity questionnaire (IPAQ), 3adjusted for order of examinations (CS+ or CS- first)
