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)].
