Fatigue (for each point worsening)	1.22 (1.10–1.37)	< 0.001
Age (each year older)	0.99 (0.97–1.01)	0.44
Female (vs Male)	2.86 (0.66–12.44)	0.16
Hours in last 7 days (for each additional hour)	0.98 (0.96–1.00)	0.05
Poor Work Performancec
Burned out (vs. not)	2.15 (1.43–3.24)	0.0002
Fatigue (for each point worsening)	1.22 (1.12–1.33)	< 0.0001
Age (each year older)	0.97 (0.95–0.98)	< 0.0001

^aFactors in the model: age, relationship status, sex, have children, work hours/week, academic degree (undergraduate [associate or BA] vs. graduate [Maters, Doctorate, other]), practice setting [inpatient vs. not], burnout, depression, fatigue, satisfaction with work-life balance. Forward stepping logistic regression w/ backwards stepping confirmatory run. Age and sex were kept in the model because these are traditional confounders; burnout was also kept in the models

^bMissed ≥ 1 day of work due to personal health in the last month

^cSelf-rated work performance score 0–8 on the World Health Organization Health and Work Performance Questionnaire
