    Snippet: The performance of theVivaDiag TM tests was compared to that of the RT-PCR tests via the "caret" R package that computed all the parameters needed (accuracy, precision, recall, kappa). Univariate and multivariate logistic regression was performed. Age was dichotomized using the median as a cut-off; days from the onset of symptoms was also transformed into a categorical variable (0-5 days, 6-8 days, 9-10 days, 11-15 days, more than 15 days). All t.....

All the analyses were carried outin R v3. 6 and results were considered to be significant when the p-value was <0.05.
