Hematologic and molecular responses to ropeginterferon alfa-2b therapy of polycythemia vera: 48-week results from a prospective study.
Trial report in International journal of cancer, 2025. The graph could read no effect estimate from its abstract, so it casts no vote on the map. Cited by 14 papers, 2 of them syntheses 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
To prevent thrombosis in patients with polycythemia vera (PV), achieving a complete hematologic response (CHR) is highly recommended in practice. In addition, a reduced JAK2 V617F mutation burden is expected to have a disease-modifying effect, and its molecular response (MR) is currently of significant interest. This study aimed to assess the association between CHR and MR in patients with PV following treatment with ropeginterferon alfa-2b. This phase 2, single-arm, open-label, investigator-initiated trial was conducted at 16 sites in South Korea. Ninety-nine patients were treated with ropeginterferon alfa-2b subcutaneously every 2 weeks, at doses of 250 μg (week 1), 350 μg (week 3), and 500 μg (week 5), until week 48. CHRs were 27% (25/94), 46% (40/87), 56% (47/84), and 63% (51/81) at 12, 24, 36, and 48 weeks, respectively. The MR rates were 32% (28/88), 36% (29/81), 49% (38/77), and 57% (42/74) at 12, 24, 36, and 48 weeks, respectively. The Phi Coefficient for the association between CHR and MR was 0.6146 (p < .0001) at 48 weeks. In the subgroup analysis, patients with hydroxyurea resistance or intolerance, and those who were hydroxyurea-naïve, had similar results in terms of the CHR. In conclusion, CHR and MR were observed to be associated in patients with PV treated with ropeginterferon.
