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
Malunion after distal radial fractures with intra-articular and extra-articular deformities is difficult to treat. We report two cases of simultaneous intra-articular and extra-articular corrective osteotomies for malunion after distal radius fractures using a patient-matched surgical guide and plate (patient-matched instruments [PMIs]) created based on a preoperative computer simulation. Both patients experienced pain and limited range of motion in the wrist and forearm. Three-dimensional models were created using CT to simulate corrective osteotomy. Two types of PMIs were created to correct the extra-articular deformity and intra-articular step-off. Intra-articular and extra-articular corrective osteotomies were simultaneously performed using the PMIs. In postoperative imaging evaluations, the average step-offs were reduced from 4.5 to 0 mm and extra-articular deformities were anatomically corrected. The average visual analog scale score decreased from 55/100 to 12/100 mm, indicating substantial pain relief. In addition, there was a notable improvement in range of motion: flexion increased from 42.5° to 62.5°, extension from 57.5° to 75°, pronation from 67.5° to 85°, and supination from 47.5° to 82.5°. Simultaneous intra-articular and extra-articular corrective osteotomy using a patient-matched surgical guide and plate is a valuable technique for correcting complex deformities and ensuring precise osteotomy.
