Developmental dysplasia of the hip in infants referred for a combined pediatric orthopedic and radiologic examination. A prospective cohort study.
Article in Journal of orthopaedics. The graph could read no effect estimate from its abstract, so it casts no vote on the map. Cited by 5 papers.
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
introductionThe study aimed to determine the proportions of infants with developmental dysplasia of the hip (DDH) and hip dislocation in infants referred for combined pediatric orthopedic and radiologic assessment, and to describe the association between DDH and different reasons of referral.
methodsA prospective study of all infants aged 0-6 months referred for a combined examination of the hips 2013-2019. The proportion of DDH and unstable hip(s) stratified by different reasons of referral were calculated. Acetabular index > 30° in radiography or Graf Type 2b or worse in ultrasonography was considered diagnostic of DDH.
resultsOf the 1,989 infants included, 17% had stable dysplastic hip(s), and 4.7% had unstable dysplastic hip(s). The proportions of infants with DDH among infants with a single reason of referral were 36% for breech position, 25% for familial disposition, 14% for hip click, 8% for asymmetry, and 3% for twins. The proportions of infants with unstable hip(s) were 14% for familial disposition, 12% for breech position, 3% for hip click, 3% for twins, and 1% for asymmetry.
conclusionThe study demonstrates that a considerable proportion of infants referred for the combined examination have radiological signs of DDH and that DDH were regularly diagnosed in infants referred due to hip click or asymmetry.
