aRed cells represent values > 2 SD below the group mean HRV difference, orange cells represent 1–2 SD below the group mean HRV difference, yellow cells represent <1 SD below or above the group mean HRV difference, light green cells represent 1–2 SD above the group mean HRV difference, and dark green cells represent >2 SD above the group mean HRV difference.
bParticipants who reported at least 1 stressor during the study period with valid HRV intervals (n = 33).
cMean difference (mean HRV for non-stressor intervals—mean HRV for stressor-intervals) = 0.37 ms; SD of mean difference = 1.99 ms.
dMean difference = 0.19 ms, SD of mean difference = 1.76 ms.
eMean difference = 0.13, SD of mean difference = 0.12.
fMean difference = 0.16, SD of mean difference = 0.15.
