Additional file 1 of Head-to-head comparison of the accuracy of saliva and nasal rapid antigen SARS-CoV-2 self-testing: cross-sectional study
Additional file 1: Material 1. Short questionnaire after performing both self-tests at home. Material 2. Short questionnaire provided 10 days after test site visit. Material 3. Specimen collection, SARS-CoV-2 diagnostic testing, and SARS-CoV-2 virus culture procedures. Table S1. 2x2 tables for primary and secondary analyses of the molecular reference test – saliva Ag-RDT comparison. Table S2. 2x2 tables for primary and secondary analyses of the molecular reference test – nasal Ag-RDT comparison. Table S3. Follow-up information of participants that were tested again within 10 days after the initial test. Fig. S1. Sensitivities with 95% confidence intervals of the Ag-RDT-molecular reference standard test comparisons at viral load cut-off for infectiousness. Fig. S2. Distribution of viral loads in participants with a positive molecular reference test, stratified by symptomatology at time of sampling. Fig. S3. Distribution of change scores in difficulty of taking a sample and difficulty of reading the test result when comparing difficulty ratings of the saliva Ag-RDT and the nasal Ag-RDT.
