Long-term results of closed reduction for developmental dislocation of the hip in children of walking age under eighteen months old.
Trial report in International orthopaedics, 2018. The graph could read no effect estimate from its abstract, so it casts no vote on the map. Cited by 20 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
backgroundDevelopmental dysplasia of the hip (DDH) diagnosed in older postnatal children can be effectively treated by closed reduction (CR) alone. However, no prospective or comparative trial to explore the differential effectiveness of CR between non-walking and walking postnatal children has yet been reported. This study investigated the clinical and radiologic outcomes of CR in the age range of interest (12-18 months old) via a prospective trial and compared these results with those of a younger age group who also underwent CR. PATIENTS AND
methodsBetween 1999 and 2009, 56 children diagnosed with DDH were enrolled. Of these, 45 were followed after CR for a period of at least seven years. The anatomical parameters of the hip/pelvis, including arthrograms, were evaluated and compared before and after CR. The final radiologic status, including the occurrence of avascular necrosis (AVN), and clinical outcomes were evaluated and compared.
resultsThe mean ages at the start of treatment were 6.11 and 15.29 months old in group 1 and group 2, respectively. None of the children required surgical open reduction during the follow-up period. The final status of hips were classified according to the Bucholz-Ogden system. Two type II hips and one type I hip were found in group 1. In group 2, two type I hips and one type III hip were observed at the final follow-up. The overall clinical outcomes were satisfactory in both groups, according to McKay's criteria. No significant differences in clinical outcomes between the two groups were found (P = 0.382). Surgery was performed for just one patient in group 2 at seven years old.
conclusionsCR in DDH for postnatal children 12-18 months old may provide similar results to the non-walking age group if performed with preliminary traction, gentle CR under general anaesthesia, percutaneous adductor tenotomy, and the minimization of forceful abduction.
