The Importance of the Number of Leads with fQRS for Predicting In-Hospital Mortality in Acute STEMI Patients Treated with Primary PCI.

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
backgroundFragmented QRS (fQRS) has been shown to be related to increased cardiovascular mortality and morbidity. However, limited data are available for evaluating the relationship between the number of leads with fQRS and in-hospital all-cause mortality in patients with acute ST segment elevation myocardial infarction (STEMI). The aim of our study is to investigate the prognostic importance of the number of leads with fQRS in acute STEMI patients treated by primary percutaneous coronary intervention (PCI).
methodsTwo hundred ten eligible patients with acute STEMI that underwent primary PCI were enrolled in this study. Each patient's 12-lead electrocardiography (ECG) taken in the first 48 hours was analyzed and the number of leads with fQRS were recorded.
resultsThe number derivations with fQRS were significantly higher in patients who developed in-hospital mortality than the patients who did not develop in-hospital mortality (2.6 ± 2.6 vs 0.9 ± 1.3; P = 0.002). Also, patients with ≥3 leads with fQRS had higher rate of in-hospital all-cause mortality (23.5% vs 7.4%, P = 0.009), higher frequency of Q wave (67.6% vs 36.9%, P = 0.001), and higher frequency of fQRS with Q wave (67.6% vs 15.9%, P < 0.001) than those patients with <3 leads with fQRS. By a multivariate regression analysis, the number of leads with fQRS was found to be an independent predictor of in-hospital all-cause mortality (odds ratio: 1.415, 95% confidence interval: 1.049-1.909, P = 0.023).
conclusionsThe number of leads with fQRS on 12-lead ECG is an independent predictor of in-hospital all-cause mortality in patients with acute STEMI treated by primary PCI.
