Investigation role of ondansetron on long QT interval among non-cardiac patients.
Article in Annals of medicine and surgery (2012), 2021. The graph could read no effect estimate from its abstract, so it casts no vote on the map. Cited by 4 papers.
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
backgroundOndansetron is one of the commonly prescribed anti-emetic in emergency department however, high dose of the drug is associated with prolonged QT interval. This study was designed to evaluate the effect of ondansetron on prolongation of QT interval among patients referred to our emergency department.
methodsIn this cross-sectional study patients referred to the emergency department of Imam Reza hospital from June 2019 to December 2019 were included. Before the administration of ondansetron 12-lead electrocardiography was performed in all the patients. 4 mg of i.v. ondansetron was administered to these patients and ECG was obtained again. QT interval was calculated automatically from the system from these electrocardiographs. Demographic data of these patients along with QT interval findings was recorded in the questionnaire and analyzed statistically using SPSS software.
resultsA total of 55 patients were included with the mean age of 58 ± 13 years, where 36 were females (65.5%) and 19 were males (34.5%). The mean QT interval before and after injection of 4 mg intravenous ondansetron was not statistically significant, p-value = 0.073. Similarly, QT interval before and after the administration of the drugs was also not significantly different among females and males, p = 0.479 and p = 0.078, respectively. The age of the patients was also not associated with prolonged QT interval, p = 0.948.
conclusionsThe findings of our study indicated that 4 mg i.v. administration of ondansetron among non-cardiac patients referred to emergency department is not associated with QT interval prolongation.
