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

Background: TANGO2 deficiency disorder (TDD) is a rare autosomal recessive condition characterized by neurodevelopmental delay, epilepsy, and metabolic crises, mainly caused by recurrent deletions in Methods: Long-read HiFi GS was performed on blood-derived genomic DNA from affected individuals in both families using the Revio system (Pacific Biosciences). Results: Homozygous deletions spanning exons 3-9 in family 1 and exons 4-6 in family 2 were identified. These recurrent deletions resulted from genomic recombination between an Discussion: This study highlights the diagnostic value of long-read HiFi GS for detecting structural variants (SVs) overlooked by standard-of-care NGS and enabling base-pair level breakpoint characterization. It provides the first evidence of retrotransposon-mediated recombination causing recurrent
