1 · What the graph read from 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.

2 · The registry

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

backgroundPhytobezoar formation is a complication of bariatric surgery and mostly occurs after laparoscopic Roux-en-Y gastric bypass (LRYGB) operations. Here, we present an extremely rare case of late phytobezoar formation following laparoscopic sleeve gastrectomy (LSG). CASE PRESENTATION: A 52-year-old woman with a body mass index (BMI) of 40.7 kg/m

conclusionsWith an increase in the number of LSG procedures performed globally, and the late-onset nature of phytobezoar formation, more cases of this complication are expected to be detected in future. Long-term postoperative follow-up alongside applying surgical methods to avoid gastric stenosis are needed to reduce the chance of phytobezoar formation in patients undergoing LSG.
