Why is the uptake of gene therapy in hemophilia less than expected?
Article in Research and practice in thrombosis and haemostasis, 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
Gene therapy has held promise to cure hemophilia since factor (F)VIII and FIX were cloned more than 40 years ago. However, scientific understanding of the adeno-associated virus, the predominant vector used in gene therapy, has been insufficient to overcome many of the hurdles encountered, resulting in failed clinical studies, marginal efficacy, unfavorable benefit/risk, or phase 3 studies that do not sufficiently support wide commercial use. However, a functional cure, defined as permanent factor levels of at least 40%, has seen durable success in some FIX gene therapy recipients. Less success has been seen for FVIII gene therapy. Additional reasons for slow commercial uptake include the need to establish complex reimbursement processes for very high-priced drugs.
