1 · What the graph read from it

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.

2 · The registry

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

Objective: To identify the genetic etiology in a neonate with persistent hypertyrosinemia and characterize the functional impact of a novel Methods: A neonate suspected of having tyrosinemia type II following newborn screening by tandem mass spectrometry was recruited, along with family members. Whole-exome sequencing (WES) was performed to identify causative variants. To validate the pathogenicity of the identified novel locus, wild-type and mutant Results: The proband exhibited persistently elevated blood tyrosine levels (>600 μmol/L) on repeated screenings. Genetic analysis revealed compound heterozygous variants in the Conclusion: A novel pathogenic variant, c.843_844inv (p. (Trp282Gly)), was identified in the
