Parameters Adjusted odds ratio (95% Confidence interval) p value
Blocked nose 3.00 (1.24, 7.19) 0.01
Rash 6.88 (1.50, 31.60) 0.01

  1. *Age, dry cough, wet cough, sore throat, running nose, blocked nose, sore eyes or eye pain, chills/rigors, myalgia/arthralgia, ear symptoms, rash, chest pain, headache, Fever ≥ 37.8°C, Fever ≥ 38.0°C, and injected pharynx were included in the analysis before non-significant terms were sequentially removed. With 48 tests, the conservative expected number of false discoveries is 2.4.
