“…Negative pools were prepared with different samples to determine whether different negative-sample composition in the pool affected the detection of positive samples. Sensitivity and sensibility were determined as described [34][35][36].…”

“…To enable appropriate inter-rater agreement, studies should focus on agreement rather than correlation indices [32][33]. In addition, future statistical analysis should consistently analyse the disease prevalence, for example, by using Negative Predictive Value and Positive Predictive Value parameters, as well as positive and negative likelihood ratios to reduce uncertainties regarding the validity of diagnostic tests [34], with the latter ratios only reported in one of the 12 studies [21]. In this way, meaningful analysis of the overall merit of AI-supported imaging-based COVID-19 detection beyond high-prevalence populations could be ensured.…”

“…The most common COVID-19 detection technique is real-time polymerase chain reaction (RT-PCR). It has a high percentage of false-negative findings and may take up to two days to receive results, while having a sensitivity range of 70 to 90 [ 9 ]; it may also produce a quite high number of false-negative effects and may take up to two days to obtain results. In some countries, it may take up to five days or more due to the overwhelming number of tests that need to be analyzed [ 4 ].…”
