Risk stratification of patients with TP53-mutated myeloproliferative neoplasms.
Article in Leukemia, 2026. The graph could read no effect estimate from its abstract, so it casts no vote on the map. Cited by 3 papers.
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
While TP53 mutations in myeloproliferative neoplasms (MPN) are associated with an increased risk of leukemic transformation, not all patients carrying a TP53 mutation progress. To better risk-stratify MPN patients with TP53 mutations, we analyzed data from 1540 patients treated at four specialized cancer centers. Among them, 1429 had wildtype TP53 and 111 had mutations in the TP53 gene. At first MPN diagnosis, 32% had polycythemia vera, 39% had essential thrombocythemia, and 25% had primary myelofibrosis. Among all MPN patients with TP53 mutations, presence of fibrosis in the bone marrow (hazard ratio (HR): 3.84, 95% CI: 1.98-7.43), multi-hit TP53 mutation status (HR: 2.74, 95% confidence interval (CI): 1.52-4.97), and higher PHANTM score (HR: 1.87, 95% CI: 1.02-3.42) were associated with worse OS in a multivariable analysis. Based on these variables, we developed a risk model to identify TP53-mutated MPN patients who are at high risk for inferior OS. Median OS from time of TP53 detection was 0.5 years in high-risk patients, compared to 2.3 years for patients with intermediate risk and 6.3 years for patients with low risk. This scoring system may help refine risk stratification for chronic phase MPN patients harboring TP53 aberrations.
