Comparison of the multichannel intraluminal impedance pH and conventional pH for measuring esophageal acid exposure: a propensity score-matched analysis

ConclusionWhile the values of each parameter regarding acid reflux are calculated as lower in MII-pH than in C-pH, there is no difference in the evaluation of the pathology between the two modalities.
