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
Congenital radioulnar synostosis (CRUS) presents a complex forearm deformity, requiring precise osteotomy planning for anatomical restoration. This study proposes an automatic osteotomy preoperative planning method for forearms with CRUS. Proximal forearm bones are first aligned with the template forearm and then a dual dimensional optimization (DDO) strategy is used to optimize the spatial transformation parameters of the distal fragment. The subsequent optimization aims to maximize the overlap of cross-sections between proximal and distal fragments. Rotational simulations are ultimately conducted to predict postoperative forearm rotational functionality. The DDO strategy effectively restores ideal forearm morphology, with maximum deviations of 1.66 and 2.13 mm for the ulna and radius, respectively. On the coronal, sagittal and transverse planes, the deformity angles of the radius were reduced to 1.35°, 1.39°, 4.83°, respectively, while those of the ulna were reduced to 1.20°, 1.03°, and 8.56°, respectively. Rotation function analysis reveals a noticeable improvement in achievable rotation range compared to plans by senior surgeons. Automated mobilization osteotomy planning, using the DDO strategy, shows potential for individualized CRUS corrective surgery, offering comprehensive and precise preoperative guidance.
