Impact of endoscopic laser cricopharyngeal myotomy on lower oesophageal sphincter physiology.
Article in Annals of the Royal College of Surgeons of England, 2024. 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
Dysphagia is a watershed symptom that localises poorly. Dividing causes of dysphagia into oropharyngeal and oesophageal does not always best serve the patient. We report the case of a patient whose diagnosis and treatment required three separate specialist referrals to two specialties, with 18 months passing between initial referral and definitive treatment. The predominant pathology was isolated upper oesophageal sphincter dysfunction that responded well to laser cricopharyngeal myotomy. Following surgery, patient symptoms resolved and lost weight was regained. High-resolution manometry showed that the upper sphincter resting pressure had fallen from 117±45 to 21±11mmHg, but the lower sphincter resting pressure had risen, albeit without symptoms, from 16±8 to 44±17mmHg (
