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
A group effect is generally assumed regarding the prolongation of the QT interval through butyrophenone antipsychotics like haloperidol. Consequently intravenous administration of benperidol is seen critically notwithstanding sparse evidence; thus benperidol and haloperidol were compared regarding their cardiac risk of prolonging the QT interval when administered intravenously for acute sedation of psychotic patients. The QT interval was measured by a 12-lead ECG. For the correction of QT values Bazett's formula was used. The resulting QTc intervals of the benperidol and the haloperidol group were compared using Mann-Whitney U-test. Our data provide statistical evidence for benperidol being less prone to cause QTc prolongation than haloperidol (p = 0.049). The results of our study indicate a more favourable risk profile of benperidol compared to haloperidol regarding QTc prolongation when administered intravenously.
