Validation of a 0-/2-Hour High-Sensitivity Cardiac Troponin Algorithm for Suspected Acute Coronary Syndrome in the Emergency Department.
Article in Journal of the American Heart Association, 2025. The graph could read no effect estimate from its abstract, so it casts no vote on the map. Cited by 3 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
backgroundWe implemented a hs-cTnI (high-sensitivity cardiac troponin I)-based algorithm for emergency department (ED) evaluation of possible non-ST-segment-elevation acute coronary syndrome within an integrated health system (Kaiser Permanente Northern California).
methodsRetrospective study of adult (18+ years) ED encounters for chest pain/discomfort with hs-cTnI testing (Access hsTnI, Beckman) at 21 medical centers between January 1, 2023 and June 30, 2024, excluding ST-segment-elevation myocardial infarction. The primary outcome was 30-day myocardial infarction or death. Sensitivity, specificity, negative predictive value, positive predictive value, and likelihood ratios were reported, with subgroup analyses by age, sex, coronary artery disease, chronic kidney disease, and ED disposition.
resultsThere were 104 025 encounters in the final cohort (median age 59 years, 45% male, 18% coronary artery disease, and 13% chronic kidney disease). The primary outcome occurred in 5.5% encounters. Rule-out criteria were present in 70% of encounters (sensitivity, 95.4% [95% CI, 94.8%-96.0%]; negative predictive value, 99.7% [95% CI, 99.6%-99.7%]; likelihood ratio, -0.05) and 7% of encounters met rule-in criteria (specificity, 96.7% [95% CI, 96.6-96.8%]; positive predictive value, 60.2% [95% CI, 59.3%-61.1%]; likelihood ratio, +24.4). In subgroup analyses, rule-out criteria negative predictive value was below 99% in stage 4+ chronic kidney disease (96.1% [95% CI, 94.6%-97.6%]) and ischemic coronary artery disease (98.6% [95% CI 98.3-98.9%]), though not among those selected for ED discharge (98.4% [95% CI, 96.7%-99.2%] and 99.1% [95% CI, 98.8%-99.4%], respectively).
conclusionsThe Kaiser Permanente Northern California non-ST-elevation acute coronary syndrome evaluation algorithm demonstrated excellent overall performance. Negative predictive value was modestly diminished in ischemic coronary artery disease or advanced chronic kidney disease, but risk was largely mitigated by ED discharge disposition decisions.
