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

backgroundPatients with chest pain are often evaluated for acute myocardial infarction through troponin testing, which may prompt downstream services (cascades) of uncertain value.

objectivesThis study sought to determine the association of high-sensitivity cardiac troponin (hs-cTn) assay implementation with cascade events.

methodsUsing electronic health record and billing data, this study examined patient-visits to 5 emergency departments from April 1, 2017, to April 1, 2019. Difference-in-differences analysis compared patient-visits for chest pain (n = 7,564) to patient-visits for other symptoms (n = 100,415) (irrespective of troponin testing) before and after hs-cTn assay implementation. Outcomes included presence of any cascade event potentially associated with an initial hs-cTn test (primary), individual cascade events, length of stay, and spending on cardiac services.

resultsFollowing hs-cTn implementation, patients with chest pain had a 2.8% (95% confidence interval [CI]: 0.72% to 4.9%) net increase in experiencing any cascade event. They were more likely to have multiple troponin tests (10.5%; 95% CI: 9.0% to 12.0%) and electrocardiograms (7.1 per 100 patient-visits; 95% CI: 1.8 to 12.4). However, they received net fewer computed tomography scans (-1.5 per 100 patient-visits; 95% CI: -1.8 to -1.1), stress tests (-5.9 per 100 patient-visits; 95% CI: -6.5 to -5.3), and percutaneous coronary intervention (PCI) (-0.65 per 100 patient-visits; 95% CI: -1.01 to -0.30) and were less likely to receive cardiac medications, undergo cardiology evaluation (-3.5%; 95% CI: -4.5% to 2.6%), or be hospitalized (-5.8%; 95% CI: -7.7% to -3.8%). Patients with chest pain had lower net mean length of stay (-0.24 days; 95% CI: -0.32 to -0.16) but no net change in spending.

conclusionsHs-cTn assay implementation was associated with more net upfront tests yet fewer net stress tests, PCI, cardiology evaluations, and hospital admissions in patients with chest pain relative to patients with other symptoms.
