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

Background: 5-10 % patients developing short bowel syndrome (SBS) have undergone a previous gastric bypass (GBP) for morbid obesity. The benefits of restoring gastric anatomy in these patients is assumed but remains unclear. Our aim was to determine the effect of gastric bypass reversal on parenteral nutrition (PN) dependence in patients developing SBS following GBP. Materials and methods: We reviewed 44 adults with SBS who had undergone GBP prior to SBS. There were 4 groups based on timing of reversal: reversal when developing SBS (n = 11), within 22 months of SBS (n = 13), greater than 22 months after SBS (n = 11), and an intact GBP (n = 9). Results: Thirty five (80 %) patients had reversal of the GBP. Nine (20 %) patients had an intact GBP, including five who underwent distal gastrectomy. Eleven (25 %) patients had bypass reversal at the time of developing SBS. There was no significant difference in PN independence at 22 months with or without GBP reversal (25 % versus 15 %). Three patients undergoing reversal 22 months after developing SBS were weaned from PN. Conclusions: The majority of patients who develop SBS following GBP for morbid obesity have the procedure reversed. The timing of reversal does not appear to be important in nutritional outcome. We were unable to determine that GPB reversal is associated with increased PN independence.
