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
Objective: To construct the symptom network of elderly patients with type 2 diabetes mellitus (T2DM) and perform association rule analysis for each symptom cluster, identify core symptoms, and explore the sentinel symptoms, to provide references for accurate and efficient symptom management. Methods: Convenience sampling was employed. Eligible elderly patients with T2DM were enrolled from the department of endocrinology, affiliated hospital of North Sichuan Medical College, Nanchong City, from March 2024 to July 2024, with data collected using the Chinese Version of Diabetes Symptom Checklist-Revised (DSC-R). The correlation was analyzed using the Apriori algorithm model to identify the sentinel symptoms of each symptom cluster, and the core symptom was identified based on the network analysis method. Results: The most prevalent symptoms were thirst and dry mouth (71.69%), general fatigue (70.78%), and frothy urine (69.58%). Regarding symptom burden severity, general fatigue (2.48 ± 1.89), asthenia (2.42 ± 1.94), and insomnia (2.39 ± 1.98) had the highest scores. Sentinel symptoms, including excessive sleepiness, limb numbness, limb swelling, and polydipsia, are characteristic manifestations of distinct symptom clusters: psychological cognition symptom cluster, peripheral nerve symptom cluster, nephropathy symptom cluster, and hyperglycemia symptom cluster. At the global level, general fatigue (r Conclusion: This study identifies general fatigue as the core symptom, with excessive sleepiness, limb numbness, limb swelling, and polydipsia emerging as sentinel symptoms, within their respective symptom clusters. From the perspective of symptom network analysis and sentinel symptoms, clinical staff can develop accurate and efficient intervention measures to improve the efficiency of symptom management and reduce the burden of symptoms in elderly patients with T2DM.
