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 aims to establish reference values for the normal bone axis in children to assess the effectiveness of corrective osteotomy procedures and guide the treatment of congenital hand malformations and post-operative axis deviations.
methodsA retrospective study was carried out between January 1, 2022, and October 9, 2024. A total of 192 individuals were included. In both abnormal and normal individuals, we measured the angles within the zone of provisional calcification and the bone axis. The metacarpal, proximal, and distal phalanx of the thumb were measured in both males and females. We calculated the average and standard deviations for both groups. These normal reference values were then compared with the abnormal reference values of patients who had types II and IV polydactyly.
resultsOur work effectively established thorough reference values for the thumb's normal axis. Considering the success of corrective osteotomies in children with congenital deformities depends mostly on these values. In polydactyly type IV, we observed a change in the angle on the side with the axis deviation. Our results highlight the need for an exact preoperative design for thumb reconstruction. It also implies the possibility of choosing the side with little or no axis deviation during operation. This strategic selection can help prevent the need for additional osteotomies or subsequent surgeries.
conclusionEvaluating and preparing corrective osteotomy treatments benefits significantly from the reference values for the proper alignment of the thumb's bones. These results enable surgeons to predict the degree of corrective osteotomy needed, thereby improving postoperative surgical results and patient satisfaction.
