Selective Use of Magnetic Resonance Imaging for Facial Palsy in the Pediatric Emergency Department.
Observational study in Pediatric emergency care, 2026. The graph could read no effect estimate from its abstract, so it casts no vote on the map. Not yet cited in PubMed.
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
objectivesThis retrospective observational study evaluated the diagnostic efficiency of routine magnetic resonance imaging (MRI) in pediatric patients with facial palsy (FP) in the emergency department (ED).
methodsPediatric patients under 18 years of age who presented with FP at the ED of a single tertiary referral hospital between January 2010 and December 2022 were included. Clinical features were assessed and used for risk stratification, which informed the diagnostic utility of the MRI.
resultsA total of 134 pediatric patients were included [mean age, 99 mo; 53.7% male (n = 72)]. Seventeen patients (12.7%) were diagnosed with central FP (CFP). Among the clinical features, additional neurological examination abnormalities emerged as the most significant risk factor for CFP (odds ratio, 86.3; P < 0.001). Risk stratification based on neurological abnormalities, underlying conditions, and associated symptoms revealed that the diagnostic utility of MRI was significantly higher in the risk group than in the no-risk group ( P < 0.001; sensitivity, 100%; specificity, 84.6%). In contrast, patients in the no-risk group who underwent MRI experienced a mean increase of 294 minutes in the ED length of stay compared with those who did not undergo imaging.
conclusionsRoutine MRI is valuable for detecting CFP in pediatric patients with neurological signs. However, its use in low-risk cases may provide limited clinical benefit, prolonging ED stay and increasing unnecessary use of medical resources. Therefore, selective imaging based on clinical indicators is recommended.
