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

introductionAlthough laparoscopic Roux-en-Y gastric bypass (RYGB) is still widely accepted as a valid procedure in the treatment of obesity and type 2 diabetes mellitus (T2DM), there continues to be a significant controversy about how long the Roux and biliopancreatic limb should be bypassed for optimum results.

aimTo assess the effect of a longer biliopancreatic limb (BPL) length on glycemic control after RYGB in T2DM patients. MATERIAL AND

methodsEighty-four patients with uncontrolled T2DM who underwent RYGB between May 2010 and April 2017 were collected from the prospectively designed database. Forty patients (S-BPL group) received BPL lengths ≤ 50 cm, including 30 cm (n = 1), 40 cm (n = 1), and 50 cm (n = 38). Forty-four patients (L-BPL group) received 100 cm BPL. Anthropometry, serum glucose and lipid metabolic parameters were measured at baseline and 1, 3, 6, 12, 24 and 36 months after surgery.

resultsComparing the two groups, there were no significant differences in anthropometric and biochemical measures, except the weight and body mass index, which were higher in the S-BPL group (85.91 ±20.32 vs. 76.25 ±16.99, p = 0.038; 31.87 ±6.61 vs. 28.7 ±4.29, p = 0.005) compared to the L-BPL group. The body weight, glucose and lipid metabolic parameters decreased over time and then remained essentially stable from the first year in both groups. Two years after surgery, the remission (HbA

conclusionsWith consistent total small bowel bypass (AL + BPL) lengths, lengthening of the BPL from 30 to 100 cm did not affect the post-RYGB glycemic control and weight loss.
