Revisiting selected risk factors and their association with ultrasonographic hip types in developmental dysplasia of the hip: a multivariate regression analysis.
Article in BMC 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
backgroundDevelopmental dysplasia of the hip (DDH) presents a diagnostic challenge due to varying risk factors (RFs) and ultrasonographic (USG) classifications. This study aimed to identify independent RFs for DDH and evaluate their association with USG hip types in a large pediatric cohort.
methodsA retrospective review was conducted on infants under six months of age from a tertiary DDH screening program (2008–2022). The study included 227 cases with DDH and 924 controls with normal hips. Univariate and multivariate logistic regression analyses were performed to assess the association of RFs with DDH and USG hip types (stable dysplastic vs. unstable hips).
resultsFemale sex (OR: 2.518), breech presentation (OR: 1.817), oligohydramnios (OR: 2.762), and foot deformities (OR: 2.262) were identified as independent RFs for DDH. Firstborn girls were significantly more likely to exhibit unstable hips (OR: 1.889, p = 0.027), underscoring their predisposition to severe forms of DDH.
conclusionThis study highlights the importance of early USG screening for infants with critical risk factors, including female sex, breech presentation, oligohydramnios, and foot deformities. Notably, firstborn girls with DDH exhibit a significantly higher risk of unstable hips, emphasizing the need for targeted screening in this high-risk subgroup.
