Prothrombin conversion accelerates with increasing age in women but not in men: findings from the Moli-sani Cohort Study.
Article in Research and practice in thrombosis and haemostasis, 2026. 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: The thrombin dynamics method has been used as an add-on analysis method for the thrombin generation test over the past years to study the balance between pro- and anticoagulant pathways. Thrombin generation test results are known to be age-dependent and gender-dependent. Objectives: In this study, we investigated the association of thrombin dynamics parameters with age and gender. Methods: Thrombin generation was measured in 17,530 individuals of the Moli-sani cohort using the Calibrated Automated Thrombinography method. Thrombin dynamics analysis was performed to quantify parameters of prothrombin conversion and thrombin inactivation. Differences in thrombin dynamics parameters in men and women and in different age groups were investigated. Additionally, reference ranges for each age and gender category were established. Results: Thrombin dynamics parameters change throughout life, and these changes differ between men and women. The total amount of prothrombin conversion decreased with increasing age (-14.4% difference between 35-44 and 85+ years of age; R = -0.234; Conclusion: The balance between prothrombin conversion and thrombin inactivation becomes more procoagulant with increasing age, but only in women. Therefore, age and gender appropriate reference values for thrombin dynamics parameters would be of interest for the clinical implementation of thrombin generation and thrombin dynamics analysis.
