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

introductionMajority of the studies comparing Roux en Y gastric bypass (RYGB) and one anastomosis gastric bypass (OAGB) are non-randomized. Moreover, few randomized studies have focussed on weight loss as the primary outcome rather than the impact on type 2 diabetes mellitus (T2DM). This randomized trial compared OABG over RYGB with the hypothesis that OAGB is not inferior to RYGB in terms of remission of T2DM.

methodsThis was an open-labelled, randomized trial in which patients having a BMI greater than 30 kg/m

resultsIn the study, 25 and 24 patients were recruited in OAGB and RYGB groups respectively. The remission rates of T2DM were similar at all timelines. The highest rate was achieved at 1 year (86.36% vs 85.71%) for both the groups and a 4-year remission rate of (72.22% vs 71.43%), for OAGB vs RYGB respectively. The % EWL was also comparable with the highest rate achieved again at 1 year (69.23% vs 66.67%) and a 4-year rate of (58.33% vs 53.33%), for OAGB vs RYGB respectively. Remission of other co-morbidities, major and minor complication rate, re-admission rate, and nutritional issues were similar in both groups.

conclusionOAGB is non-inferior to RYGB in terms of remission of type 2 diabetes mellitus, weight loss, and early and late complications with a shorter operating time.
