Statistical methods
Data distribution was evaluated by graphical method. Quantitative variables were summarised using median and interquartile range (P25-P75) and qualitative variables using frequency and percentage. Odds ratios (ORs) and 95% confidence intervals were calculated to evaluate the risk for a specific outcome. Outcomes were categorized as follows: 1. No ENT treatment or ambulatory treatment; 2. specific ENT management (minor procedure, inpatient treatment, surgical procedure). Statistical analysis was carried out using the free software R (https://www.r-project.org) with RCmdr.
RESULTS
A total of 572 consecutive subjects were prospectively included between March 16 and May 3, 2020.
