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
purposeThis study was aimed to design a patient-specific models of pediatric congenital choledochal cysts(CCC) for surgical simulation training.
methodsSeventeen children suffering from CCC were included in this study. Liver and hepatic hilum structures were generated as standard parts by traditional silicone casting after 3D printing via digital imaging. Moreover, the choledochal cyst was produced as an individualized part by the silicone shaking technique and soft resin printing. Afterwards, the two model parts were assembled for laparoscopic surgical simulation. Surgical excision and suturing, and usability were evaluated. P < 0.05 was considered to indicate a significant difference.
resultsCompared with those of the digital models, the liver well and hepatic hilum structures produced were more aesthetically pleasing. Moreover, cyst models were produced accordingly. In addition, silicone models have good mechanical properties and lower costs than resins and TPU powder, and silicone models are recommended as useful tools for presurgical simulated planning. The results also showed good feedback of cutting and suturing with good face validity and usability after the simulation was complete.
conclusionsIt is feasible that the application of the silicone shaking technique can produce a hollow individualized model of CCC for surgical simulation and medical training.
