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

purposeThis study aimed to investigate the predictive value of circulating irisin levels in discriminating the presence and severity of obstructive sleep apnea (OSA) in obese individuals.

methodsThis study was conducted on obese volunteers with and without OSA. All volunteers underwent polysomnography. Blood samples were taken on the day of the test. In addition to routine biochemistry studies, irisin levels were determined by enzyme-linked immunosorbent measurement. ROC analysis was performed to determine the predictive value of irisin.

resultsOf 100 volunteers, 75 had OSA and 25 did not. Irisin levels were significantly lower in the group with OSA than in the non-OSA group. The lowest irisin levels were determined in the group with severe OSA. Irisin levels showed high sensitivity and specificity in distinguishing between OSA and non-OSA groups. It had high sensitivity and specificity in differentiating severe OSA from other groups in subgroups, while it had low sensitivity and specificity in differentiating patients with mild and moderate OSA. In logistic regression analysis, a low irisin level was determined to be a risk factor for OSA independent of BMI.

conclusionThis study indicated that irisin levels decrease in obese individuals with OSA, correlating with the severity of the condition. Additionally, irisin levels may act as an independent predictor for OSA. The predictive value of irisin in identifying severe OSA among obese patients suggests its potential as a promising biomarker.
