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

backgroundRoux-en-Y gastric bypass (RYGB) is an effective treatment for morbid obesity. This bariatric procedure has also been noted to resolve hyperglycaemia in up to 70% of obese diabetics. We evaluated outcomes in diabetic patients undergoing RYGB in our institution, aiming to identify factors predicting diabetes remission.

methodsOne hundred ten type 2 diabetic (T2DM) patients undergoing RYGB were studied. Baseline demographics, diabetic status pre- and post-surgery and outcomes were evaluated. Outcomes were compared to a matched non-diabetic cohort.

resultsThe mean age of the patients was 45 +/- 11. The majority (70%; n = 77) were female and the mean baseline body mass index was 47 +/- 7. Mean (+/-SD range) excess weight loss at 6, 12 and 24 months was 58.3 +/- 26.4% (30.5-167%), 63.2 +/- 17.2% (0-99.2%) and 84.1 +/- 21.3% (16.5-121%), respectively. Diabetic medication was discontinued in 68.4% patients and reduced in a further 14.3%. Mean preoperative HbA1c was 7.1 +/- 2.0 and mean postoperative HbA1c 5.48 +/- 0.2. Patients with a baseline HbA1c >10 had a 50% rate of remission compared to 77.3% with an HbA1c of 6.5-7.9. The mean duration of T2DM preoperatively was 5.5 +/- 7 years. A preoperative duration of T2DM greater than 10 years was shown to significantly reduce the chances of remission (p = 0.005).

conclusionsRYGB for morbid obesity achieves significant weight reduction in diabetic patients with remission of pre-surgical hyperglycaemia in the majority. The study supports findings that a shorter duration and better control of diabetes prior to surgery corresponds to a higher rate of remission. It supports the argument for early surgical intervention in the morbidly obese diabetic patient.
