Hemostatic parameters in transgender women receiving gender-affirming hormone therapy: A shift to a cisgender female pattern?
Article in PloS one, 2025. The graph could read no effect estimate from its abstract, so it casts no vote on the map. Cited by 2 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
Transgender women have an increased incidence of venous thromboembolism (VTE) compared with cisgender individuals. However, data on hemostatic parameters in this population are scarce. We aimed to evaluate hemostatic parameters in transgender women receiving gender-affirming hormone therapy (GAHT) compared with cisgender controls. We conducted a cross-sectional study including 40 transgender women (sample size based on prior calculation), and age- and body mass index-matched cisgender women (n = 25) and cisgender men (n = 25) as controls. Blood samples were collected between 2016 and 2023. We assessed hemostatic parameters (plasminogen activator inhibitor-1 [PAI-1], free protein S, vascular cell adhesion molecule-1, antithrombin, anticoagulant protein C, prothrombin time activity, thrombin time), hormonal profile (estradiol, sex hormone-binding globulin, estrogen dose, total testosterone, and free androgen index), and inflammatory markers (fibrinogen, C-reactive protein, and leukocyte count). Transgender women (mean [SD] age, 30.6 [8.0] years; median GAHT duration, 36.5 months) and cisgender women had similar hemostatic and inflammatory parameters. Compared with cisgender men, transgender women had higher PAI-1 levels (p = 0.001) and lower free protein S levels (p = 0.023). No differences were found in other hemostatic parameters between the groups. In conclusion, transgender women on long-term GAHT had higher levels of PAI-1 and lower levels of free protein S than cisgender men, indicating a slightly more prothrombotic profile. However, their hemostatic and inflammatory parameters were similar to those of cisgender women, suggesting a shift towards a female pattern. Factors beyond GAHT may contribute to the increased risk of VTE in this population.
