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
objectiveThe aim of the study was to evaluate the cardiotoxic effects of pantoprazole in Wistar rats submitted to cardiac ischemia and reperfusion.
methodsCardiac ischemia and reperfusion was induced in rats through tourniquet of the left anterior descending coronary artery (10 min) followed by reperfusion (75 min). The incidences of ventricular arrhythmias, atrioventricular block, and lethality were evaluated by electrocardiogram analysis and compared between the control group (saline solution+cardiac ischemia and reperfusion) and the animals treated with pantoprazole 36 mg/kg (pantoprazole+cardiac ischemia and reperfusion), intravenously, immediately before cardiac ischemia (pantoprazole+cardiac ischemia and reperfusion) or before cardiac reperfusion (pantoprazole+cardiac reperfusion).
resultsThere were no differences between the incidences of ventricular arrhythmias in the groups studied. Treatment with pantoprazole before cardiac ischemia and reperfusion increased the incidence of atrioventricular block and lethality and myocardial injuries compared to the saline solution+cardiac ischemia and reperfusion group, but treatment of animals with pantoprazole before cardiac reperfusion decreased these parameters and serum creatine kinase-MB levels.
conclusionOur results indicate that when pantoprazole is administered before cardiac ischemia and reperfusion, it promotes cardiotoxicity; however, when administered before cardiac reperfusion, it promotes cardioprotection in Wistar rats.
