Racial disparities in sleep disturbances among patients with and without coronary artery disease: The role of clinical and socioeconomic factors.
Article in Sleep health, 2020. The graph could read no effect estimate from its abstract, so it casts no vote on the map. Cited by 4 papers.
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.
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
objectiveTo investigate differences in sleep quality by race in participants with and without a prior myocardial infarction (MI).
designCase-control study.
settingEmory-affiliated hospitals in Atlanta, Georgia.
participantsTwo hundred seventy-three individuals (190 Black) ≤60 years of age with a verified MI in the previous 8 months, and 100 community controls (44 Black) without a history of MI. MEASUREMENTS: Sleep quality was assessed using the Pittsburgh Sleep Quality Index (PSQI). Psychological factors were assessed using standardized questionnaires and clinical risk factors through medical history and chart review.
resultsA significant interaction existed between race and MI status on sleep quality (P= .01), such that Black individuals with a history of MI, but not controls, reported worse sleep quality than their non-Black counterparts. Among MI cases, being Black was independently associated with higher PSQI scores after adjusting for baseline demographics (B = 2.17, 95% confidence interval 1.17, 3.17, P = .006). Clinical risk factors, psychological factors and socioeconomic status (household income and years of education) all contributed equally to explain race-related disparities in sleep among MI cases. After further adjustment for these factors, the association was attenuated and no longer significant (B = 0.70, 95% confidence interval = -0.10, 1.21, P = .26).
conclusionBlack post-MI patients, but not healthy controls, have significantly poorer sleep quality than non-Blacks. This difference is driven by a combination of factors, including clinical risk factors, psychological factors as well as adverse socioeconomic conditions among Black individuals with MI.
