Quantitative DCE-MRI assessment of femoral head epiphysis perfusion after closed reduction in developmental dysplasia of the hip.

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
objectiveTo investigate femoral head epiphysis perfusion via dynamic contrast-enhanced MRI (DCE-MRI) in children with developmental dysplasia of the hip (DDH) after closed reduction, assessing correlations between perfusion parameters and enhancement grades, and their utility in identifying post-reduction ischemia. MATERIALS AND
methodsChildren with DDH undergoing closed reduction and plaster fixation were evaluated with MRI (conventional sequences, T1 mapping, and DCE-MRI) within 3 days post-procedure. Femoral head perfusion was evaluated using DCE-MRI subtraction, graded as 0 (normal), 1 (asymmetric decrease), 2 (focal decrease), or 3 (complete decrease). Perfusion parameters (K
resultsThe study included 58 DDH patients (116 hips; 68 dislocated, 48 normal). Among the dislocated side of DDH, although a marginal age difference was observed among the groups (P = 0.053), no significant differences were found in sex distribution or Tönnis grade (P > 0.05). Significant perfusion parameter differences were observed across enhancement grades (all P < 0.05), with K
