 Risk factors for acute symptom complexes*: odds ratios† (95% CI) from multivariable logistic regression models (liquor store employees only)

Upper airway symptomsChest symptomsSomatic symptoms
*Moderate or severe symptoms in previous week, defined as: upper airway: two or more of: irritated nose, throat, voice, or taste disturbances; chest: two or more of: cough, wheezing, chest tightness, breathlessness; somatic: two or more of: fever, headache, dizziness, tiredness, nausea.
†Odds ratios from logistic regression models including all the variables listed in the same model; bold indicates odds ratios greater than 1 at p<0.05.
