Incidence, Prevalence, and Survival Outcomes of Patients with Myeloproliferative Neoplasms in the United States: a SEER database analysis, years 2000-2021.
Article in Research square, 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
Myeloproliferative Neoplasms (MPNs) are rare hematologic neoplasms. The epidemiology and outcomes of these rare neoplasms warrant an update considering new diagnostic tools and advances in treatment options. NCI's Surveillance, Epidemiology and End Result (SEER)-17 registries were interrogated to analyze adult patients diagnosed with MPN [ICD-O-3 codes: polycythemia vera (PV) 9950/3, essential thrombocythemia (ET) 9962/3, primary myelofibrosis (PMF) 9961/3, and chronic myeloid leukemia (CML) 9875/3] during the years 2000 to 2021. Data of 63,242 (ET, n=24 172; PV, n= 23 456; PMF, n=6 131; CML, n=9 483) patients were analyzed. The overall incidence rate (IR) for ET, PV, PMF and CML was 1.8, 1.7, 0.5 and 0.7 per 100 000 person-years respectively. The incidence of ET, PV, and MF increased with age, and majority of cases were seen after the age of 50. 5-year Relative Survival (RS) for PMF was 50.9% in 2009, to 57.4% in 2013 and 60.6% in 2016. The median overall survival (OS) was 152 months for ET, 150 months for PV, 48 months for PMF, and 202 months for CML. Advancing age was associated with adverse survival across MPN subtypes. Survival of patients with PMF continues to improve over recent years. Important racial and gender variations exist were noted in our study.
