The Relationship Between QT Interval and Intra-Hospital Mortality in patients with Spontaneous Intracranial Hemorrhage.
Article in Advanced journal of emergency medicine, 2020. The graph could read no effect estimate from its abstract, so it casts no vote on the map. Cited by 2 papers, 1 of them a synthesis 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
introductionRepolarization abnormalities such as prolongation of QT interval and changes in ST segment and T wave are the most usual electrocardiogram (ECG) changes in patients with intracranial hemorrhage (ICH). It has recently been recommended that prolonged QTc interval raises the risk of death due to malignant ventricular arrhythmias or sudden cardiac death.
objectiveThe goal of this study was to evaluate the relationship between QT interval and death in patients with ICH.
methodThis cross-sectional study was performed on patients with ICH who referred during 2015-2017 to Poursina Hospital, Rasht, Iran. The QT interval was manually measured based on the BAZETT formula. Max QT and Max QTc and QT dispersion were the variables evaluated by the ECG of the patients. The outcome under the study was the death or survival of patients during hospitalization.
resultsFinally, 466 cases with the mean age of 69±12 years were studied of whom 68.7% were male. The average QT-Max interval was 350.4±56.5 milliseconds, and the average QTc-Max was 583.6±57.6 msec. Totally, 22.7% of the patients died. There was a significant statistical relationship between QTc-MAX and death (p=0.001). However, there was no statistically significant relationship between QT-MAX and the outcome (p=0.593).
conclusionIt is likely that, prolonged QT interval is correlated with in-hospital mortality of patients with ICH. Therefore, it can be expected that assessing ECG abnormalities, especially prolonged QTc could be valuable in these patients.
