Assessing the Causal Effect of Pulse Pressure on Migraine Risk: A Mendelian Randomization Study.
Article in Journal of pain research, 2025. The graph could read no effect estimate from its abstract, so it casts no vote on the map. Not yet cited in PubMed.
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.
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: Migraine is notably prevalent among young individuals and women, who generally demonstrate favorable arterial compliance. Pulse pressure is a reliable measure of arterial compliance; nevertheless, the association between pulse pressure and migraine is not well understood. Aim: To investigate the potential causal relationship between pulse pressure and the risk of migraine using Mendelian randomization (MR). Methods: The pulse pressure studies mainly involved participants of European descent, while the migraine studies included individuals from various parts of the UK. The primary analysis used Inverse Variance Weighted (IVW) method, supplemented by weighted median and MR-Egger regression. Validation data came from the FinnGen study. Genes linked to pulse pressure were analyzed for Gene Ontology (GO) and KEGG enrichment using the DAVID platform. Results: Single-nucleotide polymorphisms linked to pulse pressure were sourced from a GWAS database (810,865 individuals), while migraine data came from UK Biobank (13,971 cases, 470,627 controls). The IVW method showed an OR of 0.992 [95% confidence interval (CI), 0.987-0.997; Conclusion: MR analysis showed that pulse pressure causally affects migraines, potentially explaining why young people and women experience more migraines, while those with type 2 diabetes have a lower risk. Further research is needed to understand this relationship.
