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

STUDY

objectivesThe aim of this study was to determine the prevalence of insomnia and its association with clinical and psychosocial factors in a large sample of outpatients with coronary heart disease.

methodsThe sample comprised 1,082 patients, mean age 62 years (21% female), who participated in the cross-sectional NORwegian CORonary Prevention Study. Patients who were hospitalized with myocardial infarction and/or a coronary revascularization procedure in 2011-2014 responded to a self-report questionnaire and participated in a clinical examination with blood samples 2-36 (mean, 16) months later. Insomnia was assessed using the Bergen Insomnia Scale, a questionnaire based on the criteria for the clinical diagnosis of insomnia as described in the Diagnostic and Statistical Manual of Mental Disorders, fourth version. We performed bivariate logistic regressions for crude analysis and backward stepwise logistic regressions for multiadjusted odds ratios (OR).

resultsIn total, 488 patients (45%) reported insomnia, and 24% of these patients had used sleep medication in the previous week. Anxiety symptoms (OR: 5.61) were the strongest determinants of insomnia, followed by female sex (OR: 1.88), diabetes (OR: 1.83), eating fish fewer than three times a week (OR: 1.69), type D personality (OR: 1.69), and C-reactive protein ≥ 2 mg/L (OR:1.58), in multiadjusted analyses.

conclusionsInsomnia was highly prevalent in coronary heart disease outpatients. Psychological factors, lifestyle factors, and subclinical inflammation were associated with insomnia. Our results emphasize the need to identify patients with insomnia and provide appropriate management of insomnia in outpatients with coronary heart disease.
