A Genome-wide study on the genetic and causal effects of smoking in neurodegeneration.
Article in Journal of translational medicine, 2025. The graph could read no effect estimate from its abstract, so it casts no vote on the map. Cited by 4 papers.
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
backgroundSmoking represents the largest preventable risk factor for human health, yet previous studies have failed to establish conclusive evidence regarding the causal relationship between smoking and neurodegenerative diseases. This study employs genetic correlation and Mendelian randomization analyses to investigate the potential association between smoking and neurodegenerative disorders.
methodsThis study analyzed summary data from genome-wide association studies (GWAS) on smoking and neurodegenerative diseases. Genetic correlations were evaluated using linkage disequilibrium score regression (LDSC), and causal relationships were assessed through multiple Mendelian randomization methods including inverse-variance weighted (IVW), MR-Egger regression, weighted median (WME), weighted mode (WM), and simple mode (SM). sensitivity analyses were performed to examine heterogeneity, horizontal pleiotropy, and conduct leave-one-out analysis.
resultswhether an individual had ever smoked regularly (SmkInit) is positively correlated with an increased risk of Alzheimer's disease (AD) (rg = 0.134, P = 2.74 × 10⁻⁸) and negatively correlated with the risk of Parkinson's disease (PD) (rg = - 0.100, P = 1.8 × 10⁻
conclusionThis study identified significant genetic associations between smoking behaviors and neurodegenerative diseases. CigDay and SmkInit increased AD risk, while SmkCes was linked to reduced risks of PD and ALS.
