¹The “Any anger increase following task” columns give summary statistics for participants with either no change or a decrease in anger (“No”) vs. an increase in anger (“Yes”) between baseline and task. The “Return to baseline following recovery” columns give summary statistics for only those participants who showed increased anger following task, subdivided by whether or not their anger remained elevated following recovery (“No”) or returned to baseline (“Yes”). RSA means and standard deviations are presented for only those RSA measurements that temporally preceded the relevant change in anger: only baseline RSA for “Any anger increase following task”, and both baseline RSA (pooled across MDD and non-MDD participants) and task RSA (conditioned on MDD status) for “Return to baseline following recovery.” (Means for task RSA were conditioned on MDD because of evidence of a statistical interaction effect.) This is followed by odds ratios (OR) and 95% confidence intervals (CI) for the partial effects of MDD and prior RSA measurements on subsequent anger reaction and recovery as determined by logistic regression. Note that the RSA means and SDs are reported here in units of power (ms²), but the variables used in the logistic models were log-transformed and standardized, so the ORs for RSA reflect a 1 SD difference in log units.
