Especially, grade \u22652 ARE can lead to treatment interruptions, malnutrition, and even septic shock, thereby impairing patients\u2019 quality of life and survival outcomes. However, existing risk prediction models are predominantly developed based on younger populations or mixed cohorts, lacking sophisticated evaluation tools tailored to older adult patients.<\/jats:p><\/jats:sec><jats:sec><jats:title>Methods<\/jats:title><jats:p>To establish a predictive nomogram for grade \u22652 ARE in older adult cervical cancer patients undergoing radiotherapy, a retrospective cohort study of 251 older adult cervical cancer patients who received pelvic radiotherapy between January 2018 and March 2024 was conducted. Independent risk factors identified through univariate and multivariate logistic regression were incorporated into a nomogram. The model performance was validated using receiver operating characteristic (ROC) curves, calibration plots, and decision curve analysis (DCA).<\/jats:p><\/jats:sec><jats:sec><jats:title>Results<\/jats:title><jats:p>The incidence of grade \u22652 ARE in our cohort was 61.35%. Independent risk factors included age (OR\u202f=\u202f1.881, 95%CI: 1.015\u20133.484), hypertension (OR\u202f=\u202f4.577, 95%CI: 2.402\u20138.720), diabetes (OR\u202f=\u202f5.503, 95%CI: 2.206\u201313.726), Dmean_R (OR\u202f=\u202f1.309, 95%CI: 1.155\u20131.483), and lactate dehydrogenase-to-albumin ratio (LAR), (OR\u202f=\u202f1.872, 95%CI: 1.381\u20132.538). The nomogram exhibited strong discriminative ability (0.825, 95% CI: 0.774\u20130.877), and excellent calibration (Hosmer\u2013Lemeshow test,
