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
aimsSeveral contradictory definitions have been proposed for the diagnosis of periprocedural myocardial infarction (PMI) after coronary artery bypass grafting (CABG). The aim of this study was to assess the prevalence of PMI and to identify the definition of PMI with the most relevant prognostic impact. METHODS AND
resultsIn this systematic review and meta-analysis, the search was conducted in thee electronic databases (MEDLINE & PubMed Central, Cochrane Library, Embase). The primary definitions of interest comprised the universal definition of myocardial infarction (UDMI; UDMI-3/4) and Society for Cardiovascular Angiography and Interventions (SCAI) definition. The primary outcomes were the prevalence of PMI and its prognostic impact, expressed in hazard ratios (HRs) and 95% confidence intervals (CIs). The frequentist framework was employed for the primary analysis, and a secondary analysis was performed under a Bayesian framework. Ten studies were included (n = 21 203 patients). The prevalence of PMI was 17.5% (95%CI 9.5-29.8%) according to SCAI, and 3.2% (95%CI 1.6-6.2%) according to UDMI-3/4. The pooled HR of the SCAI definition for freedom from all-cause mortality was 1.60 (95%CI 1.18-2.16) and the HR was 2.54 (1.62-4.00) for UDMI-3/4 (P-for-interaction = 0.097). The posterior probability of exceeding an HR of 1 was >99% for both definitions, while the probability of the UDMI-3/4 exceeding the mean HR of SCAI was 96.4%. The results were robust across sensitivity analyses.
conclusionThe prevalence of PMI is markedly higher when diagnosed according to SCAI criteria in CABG patients. The UDMI criteria define PMI with the most relevant prognostic impact in CABG patients.
