Vonicog Alfa versus Plasma-Derived von Willebrand Factor during Hospitalization: Results of an Observational Retrospective Multicenter Study.
Observational study in Seminars in thrombosis and hemostasis, 2026. 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
Background: Available products for the treatment of von Willebrand disease (VWD) now include a new recombinant von Willebrand factor (rVWF) in addition to plasma-derived concentrates (pdVWF). However, these two therapies have never been compared directly in either preclinical studies or real-world inpatient settings. Objective: The Hopscotch Will II study examined the treatment of VWD in hospitals and compared the use of pdVWF and rVWF. Methods: Five Rare Bleeding Diseases Centers in Western France retrospectively included patients with VWD over a 48-month period. The data was collected from the BERHLINGO Research Database as well as the French Hospital database, which contains medical information from patient records. Results: Of the 866 patients evaluated in the study, 285 underwent 648 hospitalizations; 126 adult patients (VWD type 3 excluded) were given VWF concentrates during 249 of those hospital stays. rVWF was used in 61% of the cases. The majority of the hospitalizations were motivated by cutaneous-mucosal symptoms in gastroenterology, stomatology, gynecology, and obstetrics. Consumption of rVWF was lower, though the difference in total VWF consumption per stay or per patient per year was not significant: 51 (57)/34 (30) IU/kg/patient/year for pdVWF versus 40 (47)/27 (26) for rVWF (mean [SD]/median [IQR], Wilcoxon's rank sum test, Conclusion: rVWF was used in similar patient profiles and for identical procedures, but the cost of treatment with rVWF was significantly lower, regardless of whether or not FVIII was added.
