Fibrinogen genotypes and their impact on recurrence of venous thromboembolism and family history: A prospective population-based study.
Article in British journal of haematology, 2025. The graph could read no effect estimate from its abstract, so it casts no vote on the map. Cited by 3 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
Venous thromboembolism (VTE) involves blood clot formation in veins, resulting in serious health issues. Fibrinogen, a crucial clotting protein, consists of three polypeptides encoded by the fibrinogen genes: alpha (FGA), beta (FGB) and gamma (FGG). We genotyped most common missense variants in the fibrinogen genes in relation to VTE, recurrence and family history in Malmö Thrombophilia Study, including 1465 VTE patients followed for ~10 years and 429 healthy donors. FGG (rs6063) was significantly associated with increased odds of primary VTE (odds ratio [OR] = 8.2; 95% confidence interval [CI] = 1.05-63.6) after adjusting for age and sex. For recurrent VTE, Cox-regression analysis indicated a higher risk associated with FGA (rs6050) (hazard ratio [HR] = 1.8; 95% CI = 1.1-2.8), with even greater risk for unprovoked recurrent VTE (HR = 2.3; 95% CI = 1.3-4.2), surpassing the well-known factor V Leiden (FVL) (HR = 1.9; 95% CI = 1.2-3.0). Combining risk alleles from FVL and FGA (rs6050) significantly raised the risk for unprovoked recurrent VTE: ≥3 risk alleles (HR = 4.6; 95% CI = 1.9-11.3), two risk alleles (HR = 2.6; 95% CI = 1.4-4.8) and one risk allele (HR = 1.5; 95% CI = 0.8-2.7) compared to 0 risk allele. Prevalence of FGA (rs6050) risk allele was significantly higher in cases with a family history of VTE. We propose FGA (rs6050) as a novel predictor for unprovoked recurrent VTE and it may contribute to the familial occurrence of VTE.
