Emicizumab for preventing intracranial hemorrhage in infants with severe hemophilia A: a cost-effectiveness analysis.
Article in Blood advances, 2025. The graph could read no effect estimate from its abstract, so it casts no vote on the map. Cited by 3 papers, 1 of them a synthesis that pooled it.
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
abstractIntracranial hemorrhage (ICH) and resulting neurologic disability are severe complications for a subset of infants with severe hemophilia A (HA). Although prophylactic factor replacement reduces bleeding risk, it is typically delayed until after age 1 year due to risks associated with central venous access placement. Emicizumab, a subcutaneous activated factor VIII (FVIII) mimetic, has demonstrated safety and efficacy in preventing ICH in infants aged <12 months in the HAVEN 7 trial. Despite its high cost, the cost-effectiveness of emicizumab prophylaxis initiated during the first year of life for infants with severe HA is not known. We developed a Markov cohort model to compare emicizumab prophylaxis to standard care (no prophylaxis) in infants aged 0 to 1 year with severe HA without FVIII inhibitors. The analysis was conducted from a US societal perspective over a lifetime horizon across all accepted willingness-to-pay (WTP) thresholds. The primary outcome was the incremental cost-effectiveness ratio (ICER) in US dollar per quality-adjusted life-year (QALY). Emicizumab prophylaxis and standard care accrued 25.6 and 25.1 QALYs at costs of $13.12 million and $13.07 million, respectively, resulting in an ICER of $99 900 per QALY (95% credible interval [CI], 84 000-120 000). Scenario analysis examining prophylaxis with low-dose emicizumab resulted in an ICER of $19 600 per QALY (95% CI, 12 000-29 000). Probabilistic sensitivity analyses showed that standard-dose emicizumab is the cost-effective strategy in 100%, 66%, and 0% of 10 000 Monte Carlo iterations at WTP thresholds of $150 000, $104 000, and $50 000 per QALY, respectively, and in 100% across all WTP thresholds for low-dose emicizumab.
