Figure 3 Influence of CTCA on Probability of Obstructive CAD as a Function of Pretest Probability
Using the positive and negative likelihood ratios obtained from Table 2, we calculated the estimated post-test probabilities of CAD after positive and negative findings on CTCA from various estimated pre-test probabilities of CAD. Dashed lines = CTCA+; dotted lines = CTCA–. Abbreviations as in Figure 2.
