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

backgroundMany surgeons prefer a narrow gastrojejunostomy in gastric bypass believing that this provides greater weight loss. The question is whether the anastomosis remains at its initial diameter, whether it narrows or widens over time. This study tests the hypothesis that the initial diameter of the anastomosis varies over time. MATERIALS AND

methodsOne hundred obese had undergone surgery. Group A with anastomosis 1.5 cm wide and group B with anastomosis 3 cm wide. One-year follow-up was done for 83 patients. The size of the anastomosis diameter was evaluated using a balloon for cardia dilation.

resultsComparing the results of surgery with the values presented 1 year after the procedure, (i) BMI decreased from 43.3 ± 6.6 to 28.7 ± 7.0 kg/m

conclusionCalibrated anastomosis has no utility in increasing weight loss in gastric bypass.
