*Proportion of participants with characteristic demonstrating proper donning, followed by proportion of participants without
characteristic demonstrating proper donning. For the first characteristic, 34% of males and 12% of females properly donned the
respirator.
†Unadjusted odds ratio (OR) and 95% confidence interval (CI) for proper donning of disposable N95 FF respirator by participants with
characteristic compared to participants without characteristic.
‡538 of 553 participants donned an N95 FF respirator for the interviewer. For some analyses, N is <538 (as noted) because of
missing data.
§The following variables were also statistically significant in simple logistic regression analyses for this subset: male, Caucasian, ever
used mask or respirator, ever had respirator fit test, had mask or respirator at time of interview, and had certified respirator at time of
interview.
¶367 of 372 who participated in clean-up donned an N95 FF respirator for the interviewer. N is <367 because of missing data.
#The following variables were also statistically significant in simple logistic regression analyses for this subset: male, Caucasian, ever
had respirator fit test, had mask or respirator at time of interview, had certified respirator at time of interview, used certified respirator
during clean-up, and used disposable N95 FF respirator during clean-up.
**312 of 315 who used a mask or respirator during clean-up donned an N95 FF respirator for the interviewer.
