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
backgroundIn patients with obstructive coronary artery disease, early revascularization does not improve outcomes but may reduce angina symptoms. The objective of this study was to examine whether changes in health status outcomes following revascularization are explained by the extent of myocardial perfusion defects and improvement in myocardial perfusion.
methodsTwo trials enrolling stable patients with new-onset chest pain suggestive of obstructive coronary artery disease, the ISCHEMIA (International Study of Comparative Health Effectiveness With Medical and Invasive Approaches) and the Dan-NICAD (Danish Study of Noninvasive Testing in Coronary Artery Disease) trials, were analyzed. Patients with single-vessel coronary artery disease who underwent nuclear myocardial perfusion imaging (nMPI) were included. In the ISCHEMIA trial, patients with moderate/severe ischemia were randomized to either optimal medical therapy alone or optimal medical therapy and invasive angiography. The Dan-NICAD trial enrolled patients with suspected stenosis on coronary computed tomographic angiography undergoing nMPI. Test-guided revascularization blinded to nMPI was performed, and patients with initially abnormal nMPI were reassessed after 12 months. The primary outcome was the change in the Seattle Angina Questionnaire angina frequency score.
resultsIn total, 584 patients were eligible. In patients with a summed difference score of 5≤10 (n=149 [25%]) and ≥10 (n=152 [26%]), revascularization was associated with an improved angina frequency score (mean change ±SD: 16.4±20.9 and 19.0±24.1). No improvement was demonstrated in patients with a summed difference score <5. In multivariable logistic regression analysis (n=91), an increase in hyperemic myocardial blood flow at follow-up was associated with freedom from angina (odds ratio, 2.89 [95% CI, 1.04-8.70]).
conclusionsIn patients with single-vessel coronary artery disease, nMPI may identify patients more likely to experience improved symptoms from revascularization, potentially reflecting enhanced myocardial perfusion.
