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: Heterozygous familial hypercholesterolemia (HeFH) is the most prevalent inherited dyslipidemia, and it predisposes individuals to premature atherosclerotic cardiovascular disease. Genetic testing can provide a definitive diagnosis. The spectrum of causal DNA variants in Ontario patients with hypercholesterolemia is not fully defined. Methods: In Southwestern Ontario patients with a clinical diagnosis of HeFH, we performed targeted next-generation DNA sequencing and bioinformatic analysis to determine the qualitative and quantitative spectrum of pathogenic and likely pathogenic (P/LP) variants. Results: We observed 101 unique P/LP variants in 254 patients, of which 6 were novel Conclusions: This study provides a comprehensive overview of the clinical and genetic spectrum of HeFH in Southwestern Ontario. The P/LP variant diversity reflects historical colonization and later migration patterns both from across the world and interprovincially from Quebec.
