The effects of coagulation factors on the risk of Alzheimer's disease: A Mendelian randomization study.
Article in Journal of Alzheimer's disease reports. The graph could read no effect estimate from its abstract, so it casts no vote on the map. Cited by 1 paper.
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: Observational studies indicate a complex relationship between coagulation factors and Alzheimer's disease (AD). However, the current findings are inconsistent, and it remains uncertain whether a causal relationship exists. Objective: This study utilizes a Mendelian randomization analysis to investigate the causal relationships between blood levels of coagulation factors and AD risk. Methods: Eleven coagulation factors with valid instrumental variables available were evaluated. Two independent cohorts of European ancestry with AD genome-wide association study (GWAS) summary statistics were used: UK Biobank (UKB, N = 472,868) and the International Genomics of Alzheimer's Project (IGAP, N = 63,926). We primarily conducted Mendelian randomization (MR) analyses using the Inverse variance weighted (IVW). Meanwhile, the MR-Egger intercept test is used to detect horizontal pleiotropy, the Residual Sum of Squares observed (RSSobs) is used to assess the model's goodness of fit, and the leave-one-out analysis is employed for sensitivity analysis. Results: Using IVW analysis, the UKB database shows positive correlations of Protein C (PC, p = 0.002), Activated Partial Thromboplastin Time (aPTT, p = 0.019), and coagulation factor X (FX, p = 0.032) with AD, and a negative association for coagulation factor XI (FXI, p = 0.021). The IGAP database mirrors these findings for PC and FXI but not for the others. Leave-one-out analysis showed an anomaly after a single single nucleotide polymorphism (SNP) driving, yet the overall results remained stable. Conclusions: This study demonstrates that elevated levels of PC, FX, and aPTT, along with reduced levels of FXI, are causally associated with an increased risk of AD. These findings might pave the way for the diagnosis and treatment of AD.
