	Any anger increase following task		OR	95% CI
	No (n = 31)	Yes (n =68)
MDD			2.8*	1.2 – 7.2
No	21	29
Yes	10	39
Δ RSA	−0.03 (0.16)	−0.01 (0.14)	0.88	0.5 – 1.4

¹The “Any anger increase following task” columns give summary statistics for participants with either no change or a decrease in anger vs. an increase in anger, respectively, between baseline and task. The entries under the “MDD” header, form a contingency table giving participant counts. The “Δ RSA” row gives the mean and standard deviation of the within-participant difference scores in the logs of high-frequency spectral power (ms²) for the same period (task – baseline) for no-increased anger vs. increased anger due to task (main effect of within-individual RSA change pooling MDD and non-MDD participants). This is followed by odds ratios (OR) and 95% confidence intervals (CI) for the partial effects of MDD and Δ RSA on the presence vs. absence of increased anger as determined by logistic regression. The OR for Δ RSA reflects a 1 SD difference.
