Multivariable logistic regression analysis of physical (PHQ-15 ≥ 10) and chronic fatigue (FSS ≥ 3.22) symptoms after the COVID-19 outbreak according to patient care work.

Variable	Multivariable logistic analysis
	Physical symptoms		Chronic fatigue symptoms
	OR (95% CI)	P-value	OR (95% CI)	P-value
Work location
Medical institutions (COVID-19 ward, emergency room, COVID-19 intensive care unit)	2.04 (1.52, 2.78)	P < 0.001	2.14 (1.52, 3.02)	P < 0.001
Number of COVID-19 patients cared for*	0.81 (0.67, 0.94)	P = 0.026	0.82 (0.68, 0.99)	P = 0.034
Days of care for COVID-19 patients**	1.21 (1.06, 1.38)	P = 0.004	1.18 (1.02, 1.37)	P < 0.001
Average contact time with COVID-19 patients per day***	1.34 (1.17, 1.54)	P < 0.001

CI confidence interval.

*0, 1–10 patients, 11–20 patients, more than 20 patients, as the number of patients to care increases from a small group to a large group.

**0, 1–29 days, 30–59 days, 60–89 days, more than 90 days, as the number of days of care for COVID-19 patients increases from a small group to a large group.

***No, less than 30 min, 30 min–2 h, 2–6 h, more than 6 h, as the contact time with COVID-19 patients per day increases from a small group to a large group.
