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
introductionST-elevation myocardial infarction (STEMI) in patients with prior coronary artery bypass graft (CABG) represents a complex entity, with limited characterization. We sought to analyze the clinical and angiographic characteristics of post-CABG patients presenting with STEMI at a single, large referral center in the Southeastern United States.
methodsWe reviewed the STEMI alert database at the Medical University of South Carolina (MUSC). We included all patients with STEMI, as defined by the Fourth Universal Definition of Myocardial Infarction, who presented between June 2009 and December 2022. From this, we then identified those with prior CABG and analyzed their clinical and angiographic features. We compared these characteristics with patients without prior CABG. Finally, we analyzed outcomes including in-hospital complications, length of stay (LOS), in-hospital mortality, and one-year mortality.
resultsOf 836 true STEMIs, 35 (4.2%) patients had a previous CABG. The mean (standard deviation (SD)) age was 67 (12) years, and most were male patients with multiple comorbidities. Thirty-one (88.6%) underwent percutaneous coronary intervention (PCI), of which 14 (45.2%) were due to acute graft occlusion. The most common graft involved was the saphenous vein graft (SVG), seen in 13 (41.9%), while multiple-vessel PCI was the most common in those with native vessel disease, seen in six (19.4%). Most patients achieved thrombolysis in myocardial infarction (TIMI) grade 3 revascularization. In-hospital mortality occurred in two (5.7%) patients, and the mean length of stay was five days. Compared to patients without prior CABG, they were older and had greater comorbidity burdens, but survival did not differ significantly.
conclusionPatients with prior CABG constitute the minority of patients presenting with STEMI. Post-CABG patients were typically older and had a greater comorbidity burden than those without prior CABG. Clinical outcomes after PCI were similar between the two groups, although cautious interpretation is warranted, given the small sample and observational nature of our study.
