Neonatal Hereditary Fructose Intolerance: Diagnostic Misconceptions and the Role of Genomic Sequencing.
Article in JPGN reports, 2021. 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
Hereditary fructose intolerance (HFI) is a rare inborn error of metabolism due to deficiency of the enzyme aldolase B, preventing metabolism of fructose. Patients remain asymptomatic until exposed to fructose, sucrose, or sorbitol. HFI presenting as acute liver failure in the neonatal period is rare due to lack of exposure as breast milk and infant formulas are considered to be fructose free. Diagnosis can be delayed due to vague symptoms and lack of specific biomarkers. Recent advances in genetic testing have led to rapid diagnosis and favorable outcomes. We present the case of a formula-fed neonate who presented with acute liver failure where definitive diagnosis of HFI was made using expedited whole exome sequencing. Through this communication, we aim to bring attention to neonatal presentations of HFI from exposure to fructose in infant formulas and also highlight advances in rapid turnaround genomic testing in diagnosis.
