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

backgroundMorbid obesity leads to serious complications such as diabetes mellitus, arterial hypertension, and atherosclerosis. Bariatric surgery aims to reduce body weight and correct metabolic disorders and associated macro- and microvascular dysfunction. Metabolic disturbances can be assessed by biochemical markers, whereas microvascular function can be assessed by the response to provocative stimuli. The aim of this work is to quantitatively assess the cutaneous microcirculatory change caused by bariatric surgery using imaging photoplethysmography.

methodsThe study included 20 patients with obesity whose body mass index (BMI) was greater than 40 kg/m

resultsThe perfusion response to local heating was found to be significantly lower in patients with obesity before surgery compared to the control group, but 6 months after surgery, it approaches indicators of the control group, along with a decrease in BMI from 48 ± 5 to 36 ± 5 kg/m

conclusionBased on these results, we conclude that microvascular abnormalities caused by obesity could be repaired after bariatric surgery and subsequent conservative treatment.
