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

introductionSleeve gastrectomy (SG) and gastric bypass (GB) are the most commonly performed bariatric surgeries. However, there is insufficient data on which leads to greater long-term (10 year) weight loss.

methodsSubjects who underwent SG and GB from 2008-2013 were followed up at 2, 5, and 10 years post-operatively for weight and diabetes (DM) outcomes. Percentage total weight loss (%TWL), weight regain ( ≥ 20% from nadir) and DM remission rates were compared.

resultsSubjects (n = 253) who underwent SG (60.9%) and GB (39.1%) were included. The mean age was 41.4 ± 10.6 y, 39.1% were male, and the mean body mass index was 42.1 ± 9.3 kg/m

conclusionGB was able to produce greater %TWL and less weight regain than SG at 5 and 10 years post-operatively. There was no difference in long-term DM remission rates between the two surgeries.
