Risk factors for avascular necrosis of the femoral head after surgical treatment of developmental dysplasia of the hip in children: a systematic review and meta-analysis.
Review in Frontiers in pediatrics, 2026. The graph could read no effect estimate from its abstract, so it casts no vote on the map. Not yet cited in PubMed.
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
Objective: This study aims to explore the risk factors for avascular necrosis (AVN) in children with developmental dysplasia of the hip (DDH) after surgical reduction through systematic review and meta-analysis. Methods: We searched PubMed, Embase, Cochrane Library, and Web of Science for studies investigating risk factors for postoperative AVN in children with DDH. The search was conducted up to May 1, 2025. Data were analyzed using Stata version 15.1. Results: A total of 16 studies involving 1,631 pediatric patients (1,941 hips) with DDH following surgery were included. Among them, AVN occurred in 468 hips. Multivariate meta-analysis showed absence of ossific nucleus [OR = 2.60, 95% CI (1.73, 3.91), Conclusion: Based on current evidence, higher grade dislocations, absence of ossific nucleus and secondary procedures are independent risk factors for AVN following surgical treatment of DDH in children.
