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
The aim of the present study was to evaluate the feasibility of placing a coronary sinus (CS) catheter through the femoral veins of miniature swine. A total of 16 male domestic pigs (3-4 months old, 25±2 kg) were used. Firstly, the anatomic structure of the CS ostium of swine heart was observed at different angles under X-ray. The guide wire and Cobara catheter were subsequently advanced into the right atrium through the femoral vein. Subsequently, the guide wire was retracted behind the fix curve of the Cobara catheter and the catheter bent spontaneously in the absence of supporting guide wire following retraction. The catheter was then gently rotated clockwise to direct the catheter tip to the left allowing the catheter to easily be placed in the CS ostium. This method was associated with a short procedure time: The time on separation of the blood vessels was 15.5±5.8 min and the time of radiation exposure was 112±20 sec. The success rate of placing the catheter to CS ostium was 100%. Only one pig experienced a hematoma after the sheath was pulled out. All swine recovered without serious complications, such as perforation of coronary vein and pericardial tamponade. Therefore, this method of placing CS catheter is simple, safe and reliable, which may offer help for related research.
