Reducing the Duration of 24-Hour Multichannel Intraluminal Impedance-pH Monitoring for Laryngopharyngeal Reflux.

What it found
Each row is one number read from the abstract, on the scale the paper reported it, with its interval. Left of the dashed line favours the treatment, right favours the comparator. Under each row is the sentence it came from. New to these charts? A ten-minute tutorial.
The abstract states no effect estimate the extractor could read, or names no intervention and outcome on the map, so this paper lights no cell and moves no belief. It is still indexed, cited and linked below.
The trial behind it
Trials whose registry record cites this paper, or whose number appears in the abstract. A trial that started after this paper was published is citing it as background, not reporting it.
Neither the registry nor the abstract names a trial number. If this is a trial report, that itself is worth knowing.

Abstract
objectiveTo investigate whether reducing the 24-hour hypopharyngeal-esophageal multichannel intraluminal impedance-pH (HEMII-pH) monitoring duration can maintain effective diagnostic sensitivity for laryngopharyngeal reflux (LPR). STUDY
designRetrospective diagnostic accuracy study.
settingAcademic center outpatient clinic.
methodsData from 140 patients diagnosed with LPR using 24-hour HEMII-pH monitoring were reviewed. Sensitivity was assessed based on different monitoring durations and time-of-day segments. The diagnostic sensitivity of shorter durations was compared to the full 24-hour monitoring, and optimal time periods were identified.
resultsEven with just 6 hours of monitoring, a sensitivity of 81.4% was achieved, and extending it to 10 hours further increased sensitivity to 90%. When considering both monitoring duration and start time, the shortest periods achieving ≥80% sensitivity were 2:00 p.m. to 9:00 p.m., 3:00 p.m. to 10:00 p.m., and 4:00 p.m. to 11:00 p.m. For ≥90% sensitivity, the optimal monitoring periods were 10:00 a.m. to 8:00 p.m. and 11:00 a.m. to 9:00 p.m.
conclusionReducing the duration of HEMII-pH monitoring can maintain high diagnostic sensitivity for LPR, offering a more patient-friendly alternative to the 24-hour monitoring. These findings demonstrate that shorter monitoring durations can enhance patient comfort and compliance without compromising diagnostic accuracy.
