Evaluating the efficacy of endoscopic sphincterotomy on biliary-type sphincter of Oddi dysfunction: A retrospective clinical trial.
Trial report in World journal of clinical cases, 2021. The graph could read no effect estimate from its abstract, so it casts no vote on the map. Cited by 4 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
backgroundAlthough endoscopic sphincterotomy (EST) has a positive therapeutic effect on biliary-type sphincter of Oddi dysfunction (SOD), some patients still have little relief after EST, which implies that other functional abdominal pain may also be present with biliary-type SOD and interfere with the diagnosis and treatment of it.
aimTo retrospectively assess EST as a treatment for biliary-type SOD and analyze the importance of functional gastrointestinal disorder (FGID) in guiding endoscopic treatment of SOD.
methodsClinical data of 79 patients with biliary-type SOD (type I and type II) treated with EST at Affiliated Hospital of Guizhou Medical University from January 2014 to January 2019 were retrospectively collected to evaluate the clinical therapeutic effect of EST. The significance of relationship between FGID and biliary-type SOD was analyzed.
resultsSeventy-nine patients with biliary-type SOD received EST, including 29 type 1 patients and 50 type 2 patients. The verbal rating scale-5 (VRS-5) scores before EST were all 3 or 4 points, and the scores decreased after EST; the difference was statistically significant (
conclusionEST is a safe and effective treatment for SOD. For patients with type I and II SOD combined with FGID, single EST or medical treatment has limited efficacy. It is recommended that EST and medicine be combined to improve the cure rate of such patients.
