Correlations between ultrasonographic and subsequent radiographic findings of developmental dysplasia of the hips.

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
purposeThe study aimed to investigate the utility of ultrasonographic findings in predicting the subsequent radiographic parameters of developmental dysplasia of the hips.
methodsIn this 12-year retrospective cohort study, all new-born infants with a positive clinical examination or risk factors were included. They were scheduled for hip ultrasonography in the first 3 months, and subsequent radiographs at 1 year of life. The ultrasonographic images were evaluated using the Graf classification, Harcke's dynamic screening method, and Terjesen's femoral head coverage method. The radiographic images were evaluated using the acetabular index and femoral head position. The overall ultrasonographic or radiographic findings were considered abnormal if they were classified as abnormal for any of their respective parameters. The overall ultrasonographic and radiographic parameters were correlated.
resultsA total of 160 patients were included. The overall ultrasonographic and radiographic parameters showed no statistically significant difference (P=0.050). The sensitivity, specificity, and accuracy of the overall ultrasonographic parameters were 57.1%, 84.9%, and 81.3%, respectively. All three individual ultrasonographic parameters showed close correlations, with no statistically significant differences, with the overall radiographic findings and acetabular index (P>0.050). However, they showed a poor correlation, with a statistically significant difference, with the position of the femoral head (P<0.001), with the ultrasonographic parameters having an excellent negative predictive value of 100.0% for identifying an abnormal femoral head position.
conclusionThe current study suggests that ultrasonographic findings evaluated in the first 3 months of life have a close correlation with radiographic findings evaluated at 1 year of life. The ultrasonographic parameters showed an excellent negative predictive value for abnormal femoral head position on radiographs.
