Figure 1: scatter plot of sensitivity and specificity values for
antigen- and antibody-based POCTs, molecular rapid diagnostic tests, and
scores for FebriDx from the two studies that specifically evaluate
performance in screening for COVID-19 published thus far. Bubble sizes
indicate the size of the population involved in each study; the centre
point of each bubble gives the sensitivity and specificity point
estimate [Source: FIND Dx open source data on test performance(17)].
