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
backgroundIn patients with cerebral palsy (CP), spastic hip is a prevalent complication. Various surgical approaches,, including pelvic osteotomy (PO), femoral osteotomy (FO), combined femoral and pelvic osteotomy (CFPO), and soft tissue surgery (STS), have been used to address this problem. This systematic review and meta-analysis was designed to compare the radiologic outcomes of these interventions for spastic hip in patients with CP.
methodsTo identify relevant studies, databases were searched using specific keywords. Initially, duplicates were removed, then the titles and abstracts were screened, followed by a comprehensive full-text review. Data extraction took place from the studies that met the inclusion criteria. Subsequently, a meta-analysis was conducted.
resultsThe analysis of 6116 hips from 4546 patients across 81 studies demonstrated that PO significantly enhanced the center-edge angle (CEA), reduced the acetabular index (AI) and migration percentage (MP), and improved the Sharp and Tönnis angles. FO led to a substantial decrease in AI and MP, though CEA did not show a significant change, while CFPO resulted in significant improvements across AI, MP, neck-shaft angle (NSA), CEA, Sharp angle, and Tönnis angle. STS did not show significant changes in AI or CEA, but MP was notably reduced. Tone-decreasing procedures, such as selective dorsal rhizotomy and botulinum toxin injections, did not significantly alter MP, whereas guided growth techniques showed a significant reduction. MP improvements in FO decreased over time, with other radiologic parameters remaining relatively stable as follow-up increased. Age-specific trends indicated that children under 6 years primarily underwent tone-decreasing procedures and STS, while those around 7 years favored FO and guided growth, and older children (over 9 years) more commonly underwent PO, CFPO, or percutaneous osteotomy. Comparative analysis showed PO and percutaneous osteotomy were particularly more effective in reducing MP, with PO also being superior for AI improvement; whereas CFPO provided better outcomes for enhancing CEA. No significant differences were found among surgical methods for improving NSA.
conclusionsThis systematic review and meta-analysis underscores the superior efficacy of PO and CFPO in correcting spastic hip deformity in children with CP. Radiological outcomes demonstrate significant improvements following these procedures. The findings suggest that these approaches are particularly effective for complex cases where procedures such as FO, STS, or TDS may fall short. Future studies should focus on refining surgical protocols and exploring the long-term functional outcomes of these interventions.
