The clinico-radiological findings of MSUD in a group of Egyptian children: Contribution to early diagnosis and outcome.

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
backgroundMaple syrup urine disease (MSUD) is an autosomal recessive inborn error of amino acid metabolism, with unique clinico-radiological findings. This study aims to show the benefit of using the clinico-radiological findings for early diagnosis of children with MSUD, and confirming this diagnosis using the tandem mass spectrometry (MS/MS), in order to avoid deleterious outcome.
methodsA prospective cohort study conducted in the period from August 2016 to December 2020. Twenty-one children were included either by selective screening or by high-risk screening. All children had clinical and neurodevelopmental evaluation, brain magnetic resonance imaging (MRI) assessment, and blood amino acids analysis at diagnosis. Patients were followed clinically.
resultsMost children had acute onsets neuro-developmental symptoms, with wide range of brain parenchyma involvement on MRI (hyperintensity). Diagnosis of MSUD was confirmed by detecting high serum levels of leucine/isoleucine (mean value 2085.5 μmol/L) in all patients, and elevated levels of serum valine in (81%) of children. In addition, all children showed elevated leucine: alanine ratio, and leucine: phenylalanine ratio.
conclusionsThe characteristic clinico-radiological features can help in the early diagnosis of MSUD children, thus preventing the delay in laboratory diagnosis and improving their outcomes.
