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

backgroundThe aim of this study was to elucidate the molecular abnormalities in a four-generation Chinese family affected by congenital fibrinogen disorder (CFD). CASE PRESENTATION: The proband was a 5-year-old Chinese boy with CFD. Routine clotting tests revealed decreased plasma fibrinogen concentration in the proband and in his father and sister. Notably, the condition presented was clinically asymptomatic. Whole exome sequencing identified a heterozygous c.1299G > A mutation in exon 8 of the FGB gene, leading to p.Trp433* (TGG > TGA). Further Sanger sequencing revealed the presence of this mutation in his great-grandmother, grandfather, father, and sister as well.

conclusionThe FGB gene variant c.1299G > A (p.Trp433*) across four consecutive generations is associated with CFD.
