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
Background: Developmental dysplasia of the hip (DDH) in toddlers (9-18 months) presents unique challenges due to incomplete ossification and anatomical complexity. Traditional imaging modalities, including x-ray, CT, arthrography, and ultrasonography, have limitations in assessing reduction quality. This study introduces a novel approach using only two magnetic resonance imaging (MRI) parameters-axial acetabular femoral head distance (aAFD) and coronal acetabular cartilage head index (CAHI)-to evaluate the quality of closed reduction (CR) and identify risk factors for redislocation. Methods: We retrospectively reviewed 51 patients (58 hips) who underwent CR for DDH from June 2014 to June 2021. Pre- and post-CR pelvic radiographs assessed dysplasia grade, acetabular index (AI), and avascular necrosis (AVN). MRI, performed within three days post-CR, evaluated hip reduction quality using aAFD and CAHI. The reliability of these indices and their association with redislocation risk were analyzed. Results: The study cohort had a mean age of 13.7 ± 2.6 months and an average follow-up of 58.4 ± 13.5 months. CR was successful in 50 hips (86.2%), while 8 hips (13.8%) failed. Compared to failed cases, successful reductions showed significantly lower aAFD (2.4 ± 0.88 mm vs. 5.12 ± 1.70 mm, Conclusions: Closed reduction with spica casting remains an effective treatment for DDH in toddlers. Postoperative MRI evaluation using only aAFD and CAHI offers a reliable and clinically applicable method for assessing reduction quality. Larger aAFD and lower CAHI values indicate a higher risk of reduction failure, making these indices valuable for postoperative assessment and decision-making.
