SDB = SD Biosensor, BDV = BD Veritor.Of the 300 participants who had results for both POCTs and the reference test, 85 had concordant positive results from both POCTs and RT-PCR and 179 had concordant negative results. Patterns of discordance are shown in Pre-specified subgroup analyses found some variation in test performance according to certain participant characteristics reported (S1 Table 1 in Among sites that recruited at least 10 participants, sensitivity and specificity estimates were largely similar, although the prevalence of disease varied substantially between sites (S1 Fig 1 in There were two main circulating variants of SARS-CoV-2 during the study period in the UK, VOC Alpha GRY (B.1.1.7+Q.) then VOC Delta GK (B.1.617.2+AY.)
