Prognostic Value of QRS Fragmentation in Patients with Acute Myocardial Infarction: A Meta-Analysis.
Synthesis in Annals of noninvasive electrocardiology : the official journal of the International Society for Holter and Noninvasive Electrocardiology, Inc, 2016. The graph could read no effect estimate from its abstract, so it casts no vote on the map. Cited by 20 papers, 3 of them syntheses that pooled 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.
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
aimsFragmented QRS has emerged as a novel electrocardiographic parameter associated with adverse clinical events in various diseases. The aim of this study was to investigate the association of fQRS with in-hospital and long-term cardiovascular events in patients with ST-segment elevation myocardial infarction (STEMI) and non-ST segment elevation myocardial infarction (NSTEMI). METHODS AND
resultsWe searched PubMed, Embase, Web of Science, and Cochrane Library up to October 2015 for eligible studies. We selected studies with fQRS defined with 12-lead ECG during the index hospitalization of STEMI/NSTEMI. Primary outcomes were in-hospital and long-term cardiovascular events. In-hospital mortality was significantly higher in fQRS (+) group (99/733; 13.5%) compared to fQRS (-) group (47/1293; 3.6%) (OR 4.03 95% CI 1.81-8.94; P = 0.0006). Long-term mortality rate was higher in fQRS (+) group (89/473; 18.8%) compared to fQRS (-) group (54/1009; 5.3%) (OR 3.93 95% CI 1.92-8.05; P = 0.0002). In addition the frequency of long-term MACE was higher in fQRS (+) group (46.9%) compared to fQRS (-) group (14.6%) (OR 5.13 95% CI 2.77-9.51; P < 0.00001)
conclusionPresence of fQRS on admission ECG was found to be predictor of mortality, MACE, deterioration of LV function, and presence of multivessel disease in patients with STEMI and NSTEMI.
