A Hemophilia Joint Health Score-Based Model for the Economic Evaluation of Hemophilia A Prophylaxis Interventions.
Article in PharmacoEconomics, 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
BACKGROUND AND
objectiveHemophilia A is a costly, lifelong illness with multiple prophylaxis options. Previously, these options were assessed using a Peterson score-based model to simulate joint damage over time. This study built a model for the economic evaluation of hemophilia A with less socioeconomic selection bias utilizing the hemophilia joint health score (HJHS).
methodsA mechanistically defined HJHS-based state-transition microsimulation model was implemented for the cost-utility analysis conducted over a lifetime horizon from a Canadian provincial Ministry of Health perspective, with a 1.5% discount rate on (costs and outcomes), to compare the following interventions: standard half-life (SHL), extended half-life (EHL), emicizumab, and efanesocotog alfa (EA). The health states are HJHS levels, waiting for surgery, postoperative time, and death. Individuals experience bleeds, joint bleeds (increasing the HJHS), and surgery in each health state. Disutilities include injections and postoperative time. Model validation included face validity, internal validity, comparison analysis, external validity, and predictive validity. Probabilistic analysis, pricing threshold analysis, and one-way scenario analyses were completed.
resultsEA showed lower levels of hospitalizations and surgeries and an improved joint damage experience in the simulation. However, EA was not cost-effective against emicizumab, which continued to be the most cost-effective intervention. Pricing threshold analysis indicated that a price decrease would be required for EA to dominate SHL (50% decrement) and emicizumab (55% decrement).
conclusionsThis is the first cost-effectiveness model incorporating HJHS to apply sequential joint damage to hemophilia A. While EA offers clinical benefits, our analysis suggests it will not be cost-effective from a Canadian provincial Ministry of Health perspective without a significant price decrease.
