Smoke was also associated with an incremental number of symptoms (OR 1.24; <jats:italic>p<\/jats:italic>\u00a0=\u00a00.031), substance abuse (drugs or alcohol), conjunctivitis and rash (OR 5.20; <jats:italic>p<\/jats:italic>\u00a0=\u00a00.042) and the presence of at least one comorbidity with shortness of breath, tachycardia or chest pain (OR 1.24; <jats:italic>p<\/jats:italic>\u00a0=\u00a00.008). Some disease\u2010modifying therapies were associated with greater frequencies of certain COVID\u201019 symptoms (association between anti\u2010CD20 therapies and increment in the number of concomitant symptoms: OR 1.29; <jats:italic>p<\/jats:italic>\u00a0=\u00a00.05).
