Standardized mean differences plots (Love plot) comparing baseline characteristics between patients treated with and without intranasal corticosteroids (INCS) before and after propensity-score matching. Analysis stratified into 4 groups: (A) all patients who met inclusion criteria; (B) patients who did not have an inhaled corticosteroid prescription on file; (C) patients on whom a blood eosinophil count measurement was obtained at least 14 days before the date of a positive SARS-CoV-2 test, but not before 2018; (D) patients who were never diagnosed with “allergic rhinitis.” An absolute standardized difference of 0% indicates no residual bias, and values <10% indicate inconsequential bias. ACE, Angiotensin-converting enzyme; COPD, chronic obstructive pulmonary disease; NSAIDs, nonsteroidal anti-inflammatory drugs; SARS-CoV-2, severe acute respiratory syndrome coronavirus 2.
