The role of high-resolution manometry in a resource challenged service.
Article in Journal of the colleges of medicine of South Africa, 2025. The graph could read no effect estimate from its abstract, so it casts no vote on the map. Not yet cited in PubMed.
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
Background: Oesophageal high-resolution manometry (HRM) is commonly used in the evaluation of patients presenting with upper gastrointestinal tract symptoms where primary oesophageal motility disorders are suspected. At our hospital, one doctor can perform and interpret HRM, with the hospital serving a population of approximately 3 million people. There is a paucity of data on HRM findings in South Africa. Methods: This study included data from patients that underwent HRM between January 2018 and January 2023, using the hospitals electronic note-keeping system to access records. High-resolution manometry was performed for all patients using a water state catheter with 24 pressure channels. The Chicago classification version 3 was used for reporting. Results: A total of 210 patients were included in this study. The average age of patients included was 50 years (standard deviation [s.d.] ± 15.2) old with a female predominance ( Conclusion: This study, being the first of its kind in South Africa, highlights the role of HRM in the diagnosis of primary oesophageal motility disorders with ineffective oesophageal motility being the most common pathology and GORD being the most common indication for HRM. Achalasia type 1 was the common type diagnosed. Contribution: HRM, despite its scarce availability, remains an important diagnostic tool in evaluating gastrointestinal pathologies.
