Anatomophysiology of the pharyngo-upper esophageal area in light of high-resolution manometry.
Article in Journal of gastrointestinal surgery : official journal of the Society for Surgery of the Alimentary Tract, 2013. The graph could read no effect estimate from its abstract, so it casts no vote on the map. Cited by 17 papers, 1 of them a synthesis that pooled it.
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
introductionThe motility of the pharynx, upper esophageal sphincter (UES), and proximal esophagus is still poorly understood. These structures have anatomical and functional peculiarities that hinder the accurate study of their motility with the technology traditionally available. High-resolution manometry (HRM) has characteristics that make it more suitable for the study of the upper digestive tract. This study aims to evaluate in healthy volunteers, using HRM and transnasal pharyngoscopy, (1) the correlation between anatomical landmarks and HRM plots and (2) the normal values for manometric parameters of the pharynx, UES, and proximal esophagus.
methodsWe studied 40 asymptomatic volunteers with HRM (50 % male; median age, 27 years). Fourteen of those also underwent transnasal pharyngoscopy. RESULTS AND DISCUSSION: Pharyngeal peak pressure, rise time, recovery time, and duration of contraction were 128 mmHg (range, 100–164 mmHg), 197 ms (range, 169–268 ms), 385 ms (range, 285–465 ms), and 604 ms (range, 544–626 ms) at the velum and 116 mmHg (range, 97–139 mmHg), 128 ms (range, 100–156 ms), 194 ms (range, 148–219 ms), and 336 ms (range, 267–386 ms) at the epiglottis, respectively. UES extension, basal pressure, residual pressure, and duration of relaxation were 3 cm (range, 2.6–3.6 cm), 76 mmHg (range, 58–109 mmHg), 4.4 mmHg (range, 1.2–6.9 mmHg), and 678 ms (range, 636–757 ms), respectively. In the proximal esophagus, wave amplitudes at 2, 4, and 6 cm below the UES were 72 mmHg (range, 53–97 mmHg), 56 mmHg (range, 42–76 mmHg), and 48 mmHg (range, 35–59 mmHg), respectively.
conclusionsIn conclusion, normal values were established. These values may prove clinically useful and could contribute to future studies with dysphagic patients.
