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
backgroundPacing catheter-induced right ventricular (RV) perforation is a rare, life-threatening complication. Its surgical procedure typically involves lead extraction and perforation site repair via a median sternotomy. Recently, a minimally invasive approach via a minithoracotomy has been the alternative feasible approach to cardiac surgery; it reportedly prevents sternotomy-related morbidities or offers favorable cosmetic results. Herein, we present two cases in which a temporary pacing catheter-induced RV perforation was repaired via left minithoractomy. CASE 1: An 84-year-old female was admitted with a complete atrioventricular block, which was then treated by temporary pacing catheterization. Two days later, the pacing failed. Computed tomography and echocardiography revealed that the temporary pacing catheter migrated and penetrated the RV apex without pericardial effusion. Subsequently, we repaired the perforation via a left minithoracotomy through the left sixth intercostal space. Intraoperatively, a hematoma was detected on the RV apex, with the penetrated catheter covered by the epicardium. After removing the pacing catheter, we achieved hemostasis by using sheet-type hemostatic agents. CASE 2: A 91-year-old female developed a complete atrioventricular block following transcatheter aortic valve implantation. She then underwent temporary pacing catheterization. Two days postoperatively, the pacing failed because the catheter was dislocated, as confirmed by chest X-ray. Computed tomography also revealed RV perforation apparently. Meanwhile, the fixing sutures of the pacing catheter were loose. She then underwent RV repair via a left minithoracotomy in the same fashion as that of case 1. The pacing catheter perforated the RV apex apparently, with bloody pericardial effusion. After removing the pacing catheter percutaneously, we repaired the perforation site through mattress suturing.
conclusionsTwo patients with RV perforation caused by temporary pacing catheterization with stable hemodynamics were successfully treated by a left minithoracotomy.
