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

backgroundThe association of obstructive sleep apnea (OSA) with nonalcoholic fatty liver disease (NAFLD) has only been studied in selected subgroups such as the morbidly obese. We aimed to determine the prevalence and effect of OSA on NAFLD and vice versa in unselected patients attending the outpatient department.

methodsOSA was diagnosed by polysomnography, done in patients having symptoms of OSA, in patients with NAFLD attending the liver clinic. Polysomnography-proven patients with OSA attending the chest clinic were evaluated for NAFLD by ultrasonography. Anthropometry, liver function tests, metabolic syndrome evaluation and transient elastography were performed in all patients.

resultsThree (3%; 95% CI 1.03-8.45%) out of 100 patients with NAFLD (mean age 41 ± 11 years) had symptomatic OSA. Of 23 patients with OSA (mean age 46 ± 12 years,), 3 (13%) had mild, 5 (22%) moderate and 15 (65%) severe OSA. Twenty-one (91.3%; 95% CI 73.2-97.6%) patients with OSA had NAFLD, while raised hepatic transaminase levels were seen in seven (30.4%; 95% CI 15.6-50.9%). Body mass index (OR 1.21, 95% CI 1.02-1.44) and male gender (OR 4.79, 95% CI 1.12-20.48) were significant independent predictors of OSA in NAFLD. The apnea-hypopnea index (OR 1.084, 95% CI 1.002-1.172), a marker of OSA severity, was the only significant independent predictor of significant fibrosis in patients with NAFLD.

conclusionsPrevalence of symptomatic OSA in patients with NAFLD is low and is predicted by male gender and obesity. Prevalence of NAFLD in patients with OSA is very high. Significant hepatic fibrosis in patients with NAFLD is predicted by OSA independent of obesity and metabolic syndrome.
