Table 1 Data from Table 2 of the article by Malaty et al. (2022) [1] with our own calculations of the accuracy measures. It should be noted that we inverted the columns and rows of the cross table, so that “yes” and “positive” appear on the left and top of the cross table, respectively. In the cross table, the letters A, B, C and D are shown to indicate the calculation steps used to calculate the diagnostic measures
