Relationship Between Health Care Team Segregation and Receipt of Care by a Cardiologist According to Patient Race in a Midwestern State.

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
backgroundSegregation index (SI) has been associated with worsened health. However, the relationship between SI within health care teams (degree of heterogeneity between teams caring for Black compared with White patients) and cardiovascular care is unclear among adequately insured populations. We sought to assess the relationship between health care team SI, patient race, receipt of care by a cardiologist, 1-year survival, and 30-day readmission rates for Black compared with White patients admitted with heart failure, ischemic heart disease, or valvular heart disease.
methodsUsing Optum's de-identified Clinformatics Data Mart Database (CDM) from 2009 to 2020, generalized linear mixed-effects were used to analyze effects of patient race and SI on receipt of care by a cardiologist, and care by a cardiologist on 1-year survival and 30-day readmission.
resultsAmong 6572 patients (17.1% Black), the odds of receiving care by a cardiologist were 31.3% less for Black than White patients (adjusted odds ratio 0.687 [95% CI, 0.545-0.872];
conclusionsAmong patients hospitalized for heart failure, ischemic heart disease, or valvular heart disease, segregation of health care teams was not associated with receipt of care by cardiologists in Indiana hospitals. When cardiologists were included, the odds of 1-year survival increased for Black versus White patients with increasing segregation of clinicians, and segregation was not associated with 30-day readmission.
