Early Screening for Developmental Dysplasia of the Hip: Sonographic Reference Values, Risk Factors, and Treatment Considerations.
Article in International journal of neonatal screening, 2025. 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
Developmental dysplasia of the hip (DDH) is a common neonatal musculoskeletal disorder. In Germany, sonographic screening is recommended at 1-10 days of life for neonates with specific risk factors. This study aims to determine reference values for early sonographic screening and to evaluate associated risk factors. Between 2007 and 2022, 3383 neonates (6766 hips) underwent hip ultrasound according to Graf. Of these, 967 neonates were screened universally (2007-2015) and 1900 based on predefined risk factors (2015-2022). DDH was defined as ≥type IIc, according to Graf. A subgroup of 20 neonates with borderline alpha angles (51-52°) was followed up after 3-6 weeks. The mean alpha angle was 61.2° ± 5.3° (range 50.5-71.9°), and beta angle 70.8° ± 8.6° (range 53.6-88.0°). DDH prevalence was 2.5% in the universal and 3.2% in the risk-based cohort (
