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
Background: This study aims to evaluate the safety and feasibility of performing portoenterostomy in rabbits under immunosuppressive therapy. Methods: 49 New Zealand rabbits were randomly divided into two groups: the experimental group ( Results: In a study comparing portoenterostomy and choledochojejunostomy, 49 rabbits underwent surgery (24 in the portoenterostomy group and 25 in the choledochojejunostomy group). The postoperative mortality rates were 4/24 in the portoenterostomy group and 6/25 in the choledochojejunostomy group. Changes in serum bilirubin and creatinine levels suggested the occurrence of anastomotic stricture, cholangitis, and renal dysfunction in some rabbits. The portoenterostomy group showed less severe anastomotic stricture compared to the choledochojejunostomy group, and the use of immunosuppressive agents did not negatively affect the healing process. Pathological observations indicated good healing outcomes within 1 to 3 months postoperatively, despite the presence of inflammation and scar formation. Conclusions: The study demonstrates that small portoenterostomy performed under immunosuppressive therapy is a safe, simple, and technically feasible surgical approach.
