Risk factors of postoperative non-compliance behavior in elderly patients with gastrointestinal malignant tumors.
Article in BMC geriatrics, 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
backgroundElderly patients with gastrointestinal malignancies frequently exhibit postoperative non-compliance behaviors, which includes failure to persist with adjuvant therapy, attend regular follow-up appointments, and take medications strictly as prescribed. These non-compliant behaviors seriously affect the prognosis of patients.
methodsWe conducted a large-scale retrospective study in China, which enrolled 284 elderly patients who underwent surgery for gastrointestinal malignancies at Jingzhou Hospital Affiliated to Yangtze University between February 2018 and February 2023. The patients were randomly divided into a training group (198 patients, 70%) and a validation group (86 patients, 30%). Univariate and multivariate logistic regression analyses were performed to identify independent risk factors for postoperative non-compliance behaviors (P < 0.05), based on which a predictive nomogram was constructed. The model's performance was evaluated using receiver operating characteristic (ROC) curves, calibration curves, and decision curve analysis (DCA). Furthermore, all patients were followed up for 2 years, and survival curves were plotted.
resultsThe results showed that education level, disease type, history of heart disease, tumor differentiation, net family income, and living alone were independent risk factors for postoperative non-compliance behaviors in elderly patients with gastrointestinal malignancies (P < 0.05). These factors were incorporated into the construction of a nomogram prediction model. The areas under the curve (AUC) for the training and validation groups were 0.865 (95% CI: 0.814-0.915) and 0.871 (95% CI: 0.797-0.946), respectively. Calibration curve results indicated that the predicted probabilities of the model were in close agreement with the actual observed frequencies in both the training and validation groups, with mean absolute errors of 0.037 and 0.023, respectively. DCA demonstrated that the model provided significant net clinical benefit within threshold probability ranges of 0.11-0.99 for the training group and 0.41-0.91 for the validation group. Kaplan-Meier analysis showed significantly better survival in the compliance group. Disease-free survival (DFS) rates at 6, 12, and 24 months were 90.1%, 85.9%, and 79.6% versus 73.2%, 66.9%, and 62.0% in the non-adherence group (all P < 0.05). Overall survival (OS) was also significantly higher (P < 0.001), with a hazard ratio of 0.28.
conclusionOur research suggests that early intervention for elderly patients with low education levels, lesions located in the colon, comorbid heart disease, low tumor differentiation, low monthly family net income, and living alone who do not follow medical advice after gastrointestinal malignant tumor surgery can change the patient's prognosis.
