Predicting response to hypomethylating agents in myeloid neoplasms: a robust model.
Article in Annals 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
Current biomarkers and prognostic systems lack sufficient evaluation of their predictive power on HMA efficacy for myeloid neoplasms. Weighted Gene Co-expression Network Analysis (WGCNA) was employed to uncover the target module correlated with HMA response. Based on this module, Least Absolute Shrinkage and Selection Operator (LASSO) regression was applied to establish a predictive model with non-zero coefficients, termed the HMA-29 model. The magenta module was identified as the target module correlating with HMA response (R² = 0.37, p = 2 × 10⁻⁴). LASSO regression established the HMA-29 model, comprising the expression signatures of 29 genes, which stratified patients into responsive-like and resistant-like groups. HMA-29 risk scores significantly differed between HMA responders and non-responders and demonstrated superior predictive performance (AUC 0.9982, p < 0.0001). The predictive capability was validated across independent cohorts/disease subtypes/HMA drugs/sampling conditions. Notably, HMA-29 risk scores did not significantly differ between pre- and post-treatment samples. Moreover, Kaplan-Meier analysis demonstrated significant differences of disease-free survival (DFS) and overall survival (OS) between the HMA-29-defined groups. GSEA indicated that the G2M checkpoint, MYC targets, and E2F targets were positively associated with HMA-29 risk. We developed a novel predictive model for HMA response in myeloid neoplasms, demonstrating superior predictive and prognostic value compared to existing systems. Our findings provide insights into potential therapeutic strategies, including the integration of targeted therapies with HMA treatment.
