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

introductionWhile Roux-en-Y gastric bypass (RYGB) has been extensively studied in patients with type 2 diabetes mellitus (T2DM) and preserved islet function, the significance of insulin resistance in guiding RYGB treatment remains unclear. This study aimed to evaluate the efficacy of RYGB in T2DM patients with a low body mass index (BMI, 27.5-35 kg/m²), insulin resistance, and impaired β-cell function.

methodsA retrospective cohort of 34 T2DM patients with low BMI who underwent RYGB at our institution was analyzed. Insulin resistance was assessed using hyperinsulinemic euglycemic clamp. The indicators related to glucose and lipid metabolism were also assessed and collected at baseline and 12 months postoperatively.

resultsSignificant reductions in BMI and HbA1c were observed within 12 months post-surgery (P < 0.05). Fasting plasma glucose decreased from 9.40 ± 3.12 mmol/L to 5.87 ± 2.67 mmol/L (P < 0.05). Complete remission rates were 31.25% for T2DM, 100% for hypertriglyceridemia, and 70% for hypertension. Multivariable logistic analysis identified shorter diabetes duration (odds ratio [OR] 0.89, 95% confidence interval [CI] 0.83-0.95, P = 0.025), higher BMI (OR 1.14, 95% CI 1.06-1.34, P = 0.033), and lower peripheral glucose disposal rate (OR 0.95, 95% CI 0.93-0.97, P = 0.043) as independent predictors of diabetes remission.

conclusionsPatients with T2DM and low BMI who have insulin resistance may still benefit from RYGB, even if they exhibit impaired β cell function. Shorter duration of diabetes, higher BMI and lower peripheral glucose disposal rate were independent predictors of diabetes remission after RYGB.
