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

Roux-en-Y gastric bypass (RYGB) is one of the most performed bariatric procedures worldwide. Although the complication rate is low, the benefits gained from surgery outweigh many risks, including malnutrition, electrolyte imbalances, and recurrent marginal ulcers. Since RYGB changes the length of the functioning small bowel and because small bowel length is highly variable, the outcomes, which include weight loss, resolution of medical problems, and development of nutritional deficiencies or limb length, can be highly variable. We present a case of laparoscopic reversal of RYGB. A 52-year-old female patient presented with diarrhea, electrolyte imbalance, and severe weight loss 12 months after RYGB, and a reversal of RYGB was needed to overcome these severe issues. After surgery, she made a full recovery. On follow-ups, she is doing well.
