The ER Stress-related Gene Prognostic Signature for Predicting Chemosensitivity and Prognosis in AML.
Article in Recent patents on anti-cancer drug discovery, 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
introductionAcute myeloid leukemia is characterized by high heterogeneity, and the current European Leukemia Net (ELN) risk stratification system is not universally applicable to all AML patients, requiring approximately three weeks for testing.
aimThis study aimed to develop an applicable prognostic tool capable of addressing the limitations of current methods. We selected AML patients from the clinic and TCGA database to explore the role of ER stress in response to chemotherapy.
methodsPatients from the TCGA database were employed as the training cohort, and two GEO datasets were used as external validation cohorts. Univariate/multivariate COX and LASSO regression were exemplified to establish the prognostic model. Kaplan-Meier and timedependent ROC were used to assess and compare the efficiency of the model with ELN stratification and other models. In the training cohort, we selected 5 ER stress-related genes to predict chemosensitivity and establish the ERS-5 prognostic model. RESULTS AND DISCUSSION: The model successfully predicted the overall survival of patients (p < 0.0001, HR = 4.86 (2.79-8.44); AUC = 0.83). It was verified in validation cohorts and could further stratify the risk of various AML subgroups. It also enhanced the ability of ELN to predict the response of patients with AML to main chemotherapeutic drugs. Finally, an "ERS-5" risk score was constructed by the nomogram based on the ERS-5 model and age.
conclusionConsequently, in this study, the ERS-5 model was constructed, which allowed more rapid (about 3 hours) and accurate risk stratification and complemented the ability of ELN to assess chemosensitivity.
