NWTC fMRI participants demographics report

N = 98 (n=97 scanned; n=1 who couldn’t tolerate scanner*)

_{*I’m including NWTC-034 in the table because they have Visit 3 data but I can take them out if you want}

Demographics table

	Low-exposed (N=33)	PTSD (N=32)	Resilient (N=33)	Overall (N=98)
Note: Participants with 'Unspecified' race provided ethnicity but not race, due to survey design of this question. BDI-II total is missing for two participants because they skipped one or more items. Missing data will be addressed by multiple imputation in final analyses.
