    Document: The statistical analysis was performed using SPSS software for Windows version 15.0 (SPSS, Inc, Chicago, IL). Descriptive statistics were expressed as mean ± standard deviation or median (minimum-maximum) for continuous variables and as the number of observations and percentage for categorical variables. Differences in categorical variables were assessed by Pearson's chi-square test or Fisher's exact test. Statistical agreement between virus positivity in DCR biopsy specimens and nasal swab specimens was tested by the kappa coefficient (κ). A value of p < 0.05 was considered statistically significant.
