Fig 6. Accuracy of real-time PCR (comparison with fecal tests): ROC curve.

Of note, the only study using a CRS (including serology) to assess the accuracy of real-time PCR demonstrated a sensitivity of 56.8%[20], which is almost the same value found with the meta-analysis. On the other hand, the only study using a Bayesian approach [11] demonstrated an extremely low sensitivity (11.6%) of real-time PCR.
