Asymmetrical thigh creases or isolated thigh crease may be a false positive sign with low predictive value in the diagnosis of developmental dysplasia of the hip in infants: a prospective cohort study of 117 patients.

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
backgroundThe clinical importance of asymmetrical thigh creases in the diagnosis of developmental dysplasia of the hip (DDH) in infants remains controversial. The aim of this study is to investigate the association of asymmetrical skinfolds of the thigh as the only clinical finding with the DDH in infants.
methodsOne hundred and thirty-four infants between January 2010 and December 2015 were referred to our clinics for DDH with the only clinical sign being asymmetrical or isolated thigh creases and met the inclusion criteria of the study. Patients with another clinical sign for DDH in our initial evaluation, those infants suspicious for syndrome and those older than 6 months were excluded. Finally, 117 patients had undergone clinical and ultrasound evaluation and were included to statistical analysis.
resultsThere were 82 females and 35 males, with mean age of 2.2 months old. In 96 of the 117 infants (82.1%), there were provocative skin creases in the opposite thigh after a little pressure of the thigh by the examiner during the evaluation. Three of the babies (3.1%) with provocative skin creases and 1 (4.8%) with true isolated thigh crease had immature hips in ultrasonography. Positive predictive value for DDH of an isolated or asymmetrical thigh crease was 4.55% (95% CI 0.83-21.36%), and negative predictive value was 96.97% (95% CI 94.75-98.27%). Sensitivity of skinfold asymmetry found to be 25% (95% CI 0.63-80.59%), and specificity was 82.05% (95% CI 73.88-88.53%) for DDH.
conclusionThe positive predictive value of asymmetrical or isolated thigh creases for DDH in infants was found to be low, as the majority of hips with normal clinical examination and asymmetry in thigh skinfolds seemed to be normal. Moreover, in-depth evaluation of the patients could highlight new provocative thigh creases in the opposite thigh, which could limit the referrals to expert physicians to exclude DDH. LEVEL OF EVIDENCE: Level III.
