Design outcomes

Primary

MeasureTime frame
The primary outcome is the Sensitivity, Specificity and Diagnostic Odds Ratio of RRVB, either alone or in combination with a symptom inventory, to identify COVID-19 positive patients vs. asymptomatic healthy controls on Day 1Timepoint: Day 1 to 14, each day

Secondary

MeasureTime frame
Mean and 90% confidence interval of the correlation coefficient distribution between RRVB-based scores and self-reported respiratory symptom burden pooled across study days within individual COVID-19 patientsTimepoint: within 3 Months;Sensitivity, Specificity and Diagnostic Odds Ratio of RRVB, either alone or in combination with a symptom inventory, to discriminate COVID-19 positive vs. symptomatic COVID-19 negative patients on Day 1Timepoint: Day 1 to 14, each day
