Causal Relationships Between Neuropathic Pain and Alzheimer's Disease: A Multi-Omics Mendelian Randomization Study with Exploratory Evidence of a Potential Protective Role of Diabetic Neuropathy.
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: Neuropathic pain (NP) frequently co-occurs with Alzheimer's disease (AD), yet the causal relationship and underlying molecular mechanisms between the two remain unclear, necessitating further investigation to elucidate their intrinsic connection. Methods: This study employed a bidirectional two-sample Mendelian randomisation (MR) approach to systematically analyse the association between six NP subtypes and AD. Concurrently, functional annotation and transcriptomic analysis were conducted using the GTEx v10 and GEO GSE156184 databases to explore potential molecular mechanisms. Results: The study revealed a significant inverse causal effect of diabetic neuropathy (DN) on AD risk (OR=0.86, 95% CI: 0.77~0.95, Conclusion: This study provides the first evidence that DN may exert a protective effect against AD by regulating the aforementioned tissue-specific genes and associated pathways. This finding challenges the conventional understanding that chronic pain exacerbates AD and offers novel potential targets for developing therapeutic strategies. However, due to population limitations in the study, further experimental validation remains necessary.
