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
backgroundIn recent years, the use of ultrafine choledochoscopy has gradually increased in the treatment of cholelithiasis. However, stone incarceration and residual spasm of the sphincter of Oddi may be inevitable when an ultrafine choledochoscope is used alone.
aimTo investigate the safety and feasibility of ultrafine choledochoscopy combined with low-dose atropine in the treatment of Oddi intersphincter stones.
methodsSeventeen patients with Oddi intersphincter stones were retrospectively analyzed. The perioperative clinical data and follow-up information were collected.
resultsAmong the 17 patients, 3 were male and 14 were female. The mean age was 40.6 ± 13.9 years, and the mean diameter of the common bile duct was 7.8 ± 1.3 mm. All patients successfully underwent Oddi intersphincter stone removal using a combination of ultrafine choledochoscopy and low-dose atropine. No serious complications, such as postoperative hemorrhage, pancreatitis or bile leakage occurred in the 17 patients. During the one-year follow-up, none of the patients experienced stone recurrence.
conclusionUltrafine choledochoscopy combined with low-dose atropine is safe and feasible for the treatment of Oddi intersphincter stones.
