Figure 1. Characterization of asthma in adult COVID-19 inpatients. (A)
Prevalence of asthma in COVID-19 and in the KNHANES. (B) Prevalence by
age group in COVID-19 and in the KNHANES. (C) Univariate analysis of
clinical outcomes according to asthma. (D) Death and ongoing care
according to the asthma subgroups. (E) Forest plot showing odds ratios
(ORs) of asthma for the clinical outcomes. ORs are adjusted for age,
sex, body mass index, smoking history, underlying comorbidity, and
treatment for COVID-19 by multivariate logistic regression model.
Abbreviations: KNHANES = the Korea National Health and Nutrition
Examination Survey; COVID-19 = coronavirus disease-2019; ICU = intensive
care unit; BMI = body mass index; PCR = polymerase chain reaction;
SARS-CoV-2 = severe acute respiratory syndrome coronavirus 2.
Figure 2. Forest plot showing odds ratios (ORs) for risk factors for
delayed viral clearance (>30 days). (A) Total patients (N =
1321; the delayed viral clearance group = 415). (B) Mild (no activity
limitation) group (N = 938; the delayed viral clearance group = 281).
ORs are adjusted for age, sex, body mass index, smoking history,
underlying comorbidity, and medication for COVID-19 by multivariate
logistic regression model.
Abbreviations: COVID-19 = coronavirus disease 2019; Hb = Hemoglobin; CRP
= C-reactive protein.
