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

High blood pressure (BP) represents a major cause of life-threatening cardiovascular conditions. GWAS have identified >2000 BP-associated signals. BP-GWAS usually analyze each BP trait individually. However, multi-trait GWAS may yield novel loci and improve polygenic risk scores (PRS) prediction. We explored whether multi-trait BP-GWAS can: (i) find novel loci undetected by single-trait GWAS; (ii) increase heritability estimates; (iii) improve PRS prediction of hypertension within the Lifelines Cohort Study. We investigate the utility of multi-trait GWAS approaches of correlated BP traits (systolic BP, diastolic BP, pulse pressure). We tested two multi-trait methods inputting results from the latest N > 1 million single-trait BP-GWAS: (a) Multi-Trait Analysis of GWAS (MTAG); (b) genomic structural equation modeling (GenomicSEM); and compared results with single-trait results. We only identified one novel locus from multi-trait GWAS: ZNF268. Neither heritability estimates nor PRS performance improved using multi-trait GWAS. In this scenario of complete sample overlap across BP-GWAS, we observed little gain in results from multi-trait BP-GWAS over single-trait BP-GWAS. Our findings quantify the limited benefit of multi-trait methods under this specific setting. Future BP genetic discoveries are more likely to come from larger GWAS adding new cohort data. However, conclusions may differ for other traits, depending on trait-specific genetic architecture.
