Table 2 Spearman correlation coefficient of the logit of TPR versus logit of FPR

From: Meta-analysis to compare the accuracy of GeneXpert, MODS and the WHO 2007 algorithm for diagnosis of smear-negative pulmonary tuberculosis

Test Spearman correlation coefficient p- value
GeneXpert 0.232 0.405
MODS 0.4 0.600
WHO 2007 algorithm 0.9 0.037
  1. Note: The logit of the true positive rate is the natural log of [true positive rate/(1-true positive rate)]. The logit of the false positive rate is the natural log of [false positive rate/(1-false positive rate)].
