Cost-effectiveness analysis of ropeginterferon alfa-2b for the management of patients with polycythemia vera in Japan.
Article in International journal of hematology, 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
objectiveTo verify the clinical benefit of ropeginterferon alfa-2b (ropegIFN) and evaluate its cost-effectiveness compared with hydroxycarbamide or ruxolitinib for patients with polycythemia vera (PV) under the National Health Insurance (NHI) system in Japan.
methodsThe cost-effectiveness of ropegIFN compared with hydroxycarbamide or ruxolitinib was evaluated for patients with PV requiring cytoreductive therapy (without prior cytoreductive therapy) and resistant or intolerant to hydroxycarbamide. According to previous reports, patients with PV who achieve a molecular response with a JAK2V617F allele burden < 10% tend to maintain hematologic responses even after discontinuing interferon treatment. Therefore, in these analyses, patients who achieved a molecular response with JAK2V617F burden < 10% discontinued ropegIFN treatment.
resultsCompared with hydroxycarbamide, ropegIFN yielded an incremental effectiveness of 0.440 quality-adjusted life years (QALYs), indicating a higher QALY gain. The incremental costs were 128,001,730 yen, and the incremental cost-effectiveness ratio (ICER) was 291,092,030 yen/QALY. Compared with ruxolitinib, the incremental effectiveness of ropegIFN was 1.278 QALYs, while the total costs were reduced by 18,025,182 yen, which resulted in a dominant ICER.
conclusionsThese results suggest that ropegIFN may be cost-effective compared with ruxolitinib in patients with PV who are resistant or intolerant to hydroxycarbamide under the NHI system in Japan.
