Emicizumab in Children with Severe Hemophilia A.
Observational study in Indian journal of pediatrics, 2025. 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
objectivesTo assess the effectiveness and tolerability of emicizumab prophylaxis in hemophilia A (HA). Emicizumab is a novel therapeutic drug which is the first and only non-factor replacement agent licensed for use in people with HA.
methodsPediatric patients aged 1 mo to 12 y with severe HA and frequent / life threatening bleeding events, with or without coagulation protein factor VIII inhibitors were enrolled (n = 18) in this observational pre-post study. Patients were switched from therapy involving on-demand or prophylactic factor VIII/bypassing agents/immune tolerance induction to emicizumab prophylaxis and followed up for 52 wk.
resultsOne year before initiating emicizumab, a total of 229 bleeding events occurred among the enrolled children. After emicizumab prophylaxis, 5 patients had one episode of bleeding event each with a mean bleeding duration of 1.2 d in one year. The mean annualized bleeding rate significantly reduced from 12.7 ± 8.61 events pre-emicizumab prophylaxis to 0.28 ± 0.46 events post-emicizumab prophylaxis (p < 0.001). Out of the total cohort (n = 18), 72.2% of patients (n = 13) had no bleeding events (95% Confidence interval: 46.4-89.3) while on emicizumab. The mean annualized joint bleeding rate reduced from 9.72 ± 7.44 to 0.17 ± 0.38 (p < 0.001). The target joint resolution was 100% and no adverse events were noted.
conclusionsEmicizumab was found to be effective and safe as a prophylactic agent for the treatment of severe HA with and without factor VIII inhibitors. Emicizumab prophylaxis can optimize treatment outcomes and promote a better quality of life in children with severe HA.
