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

purposeMorbid obesity represents the most severe form of obesity and surgical intervention would be its only successful treatment. Bariatric surgery could generate modifications in carbohydrate metabolism and in lipid profile plus lipoprotein-associated proteins and enzymes, such as lipoprotein-associated phoslipase A

methodsThirty-seven patients with morbid obesity were recruited. Evaluations were performed before (T0) and 1 (T1) and 6 (T2) months after surgery. Glucose, insulin, high-sensitivity C-reactive protein (hsCRP), triglycerides, total cholesterol, high-density lipoprotein cholesterol (HDL-C), low-density lipoprotein cholesterol, apolipoproteins (apo) A-I, and B plus Interleukin 1β and 6 levels in addition to CETP, Lp-PLA2, and PON 1 activities were determined.

resultsBody mass index decreased at T1 and T2 (p < 0.01). An improvement in all markers of insulin resistance (p < 0.05) was observed at T1. hsCRP levels diminished at T2 (p < 0.05). Triglyceride levels decreased at T1 and T2 (p < 0.05). HDL-C and apo A-I showed a decrease at T1 which was completely reversed at T2 (p < 0.05). Lp-PLA

conclusionsThese results would be indicative of a favorable effect of bariatric surgery on markers of carbohydrate metabolism and cardiovascular disease lipid risk factors.
