Symptom Clusters and Sentinel Symptoms in Heart Failure Patients: A Cross-Sectional Survey.
Article in International journal of general medicine, 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
Purpose: To explore the symptom clusters of heart failure (HF) patients, identify the sentinel symptom of each symptom cluster, and provide a basis for the implementation of precise symptom management. Patients and Methods: The study participants were recruited using convenience sampling from inpatients admitted to the cardiology department between November 2024 and January 2025, including patients admitted for acute HF, chronic HF, and acute decompensation of chronic HF. The General Information Questionnaire and the Memorial Symptom Assessment Scale were used for the survey. Symptom clusters were explored using principal component analysis, sentinel symptoms were explored using the Apriori algorithm. Results: A total of 354 HF patients participated in the study. Four symptom clusters were identified in HF patients: the nocturnal respiratory distress symptom cluster, the low perfusion symptom cluster, the upper airway irritation symptom cluster, and the gastrointestinal symptom cluster. Three sentinel symptoms were explored: waking up breathless at night, sweating and cough. Conclusion: HF patients have a variety of symptoms in the form of four symptom clusters, waking up breathless at night, sweating and cough are the sentinel symptoms. Medical staff can take sentinel symptoms as the focus of symptom cluster evaluation and targeted intervention, which can improve the efficiency of symptom cluster management and reduce patients' symptom burden.
