1. Key: The odds ratios and 95% CIs were derived from univariate logistic regression models. In models (a): the outcome is the presence of the specific symptom, HCoV positivity is the covariate, and the reference category is “HCoV positive”. In models (b), the outcome is the presence of the specific symptom, the covariate HCoV has three categories (HCoV positive with a monoinfection, HCoV positive with coinfection, and HCoV negative), and the reference category is “HCoV positive with monoinfection”.
