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

backgroundRecent studies showed that fetuin-A and matrix metalloproteinase-7 (MMP-7) are type 2 diabetes mellitus (T2DM)-associated markers. Bariatric surgery not only reduces body weight but also improves T2DM. This study aimed to investigate the changes of fetuin-A and MMP-7 in obese subjects with and without T2DM after bariatric surgery.

methodsWe enrolled 130 obese subjects that received bariatric surgery, including 41 Roux-en-Y gastric bypass (RYGB), 67 mini-gastric bypass (MGB), and 22 sleeve gastrectomy (SG) patients. Forty-three patients suffered from T2DM prior to surgery. The fasting serum fetuin-A and MMP-7 levels were measured before and 1 year after surgery.

resultsOnly five of 43 patients remained diabetic after surgery. Preoperative T2DM patients had higher fetuin-A and MMP-7 levels than non-T2DM subjects. RYGB, MGB, and SG all decreased the fetuin-A levels 1 year after the operation. The MMP-7 levels were not changed after RYGB, MGB, or SG. In multivariate analyses, the preoperative fetuin-A was significantly related to the diastolic blood pressure (DBP) and glycosylated hemoglobin (HbA1c), while the postoperative fetuin-A was independently related to the waist-to-hip ratio and HbA1c. Moreover, the preoperative MMP-7 level was significantly related to age, DBP, aspartate transaminase, alanine transaminase, and gamma-glutamyl transferase (rGT), while the postoperative MMP-7 level was independently related to age and rGT.

conclusionsThe fetuin-A and MMP-7 levels are both higher in obese T2DM than non-T2DM subjects. The level of fetuin-A is reduced after RYGB, MGB, and SG, but the level of MMP-7 remains unchanged.
