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
Objectives: The retroflex position is crucial for the success of pancreato-biliary cannulation in patients with Roux-en-Y gastrectomy (RYG). We aimed to investigate the factors associated with forming the retroflex position in patients with RYG, including short-type single-balloon enteroscope (sSBE) and short-type double-balloon enteroscope (sDBE). Methods: 119 consecutive patients who underwent endoscopic retrograde cholangiopancreatography (ERCP) after RYG were enrolled. All the procedures were performed using sSBE (SIF-H290S; Olympus Medical Systems, Tokyo, Japan) or sDBE (EI-580BT; Fujifilm, Tokyo, Japan). The clinical outcomes of ERCP were compared between patients undergoing ERCP with sSBE ( Results: The overall cannulation success rate was 76.7% in patients with RYG. Multivariate analysis revealed that retroflex position was the only independent factor associated with successful cannulation (Odds Ratio [OR] 6.996, 95% Confidence Interval [95%CI] 2.604-20.703, Conclusions: The retroflex position was the most useful factor for the cannulation success rate in patients with RYG. Moreover, we first demonstrated that sSBE was more useful than sDBE for forming the retroflex position. Thus, sSBE may be better for patients with RYG through easier formation of the retroflex position than sDBE.
