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
Context: Symptom clusters and symptom networks can potentially enhance the precision in managing symptoms. However, limited research has been conducted on the symptom network experienced by patients infected with Severe Acute Respiratory Syndrome Coronavirus 2. Objectives: To identify the composition of symptom clusters in SARS-CoV-2 infected patients, establish a symptom network to explore the centrality indices, and investigate independent risk factors influencing the occurrence of symptom clusters. Methods: Between February 2022 and June 2023, a total of 418 patients diagnosed with SARS-CoV-2 infection were recruited in the Second Affiliated Hospital of Chongqing Medical University. A symptom questionnaire was utilized to assess three dimensions encompassing a comprehensive range of 40 symptoms. Principal component analysis was employed to identify distinct symptom clusters, while network analysis elucidated the interconnections among these symptoms. Univariate analysis and multiple linear regression analysis were conducted to investigate the factors influencing the manifestation of these symptom clusters. Results: Eight symptom clusters were identified, namely the nasopharyngeal-related symptom cluster, the circulatory-related symptom cluster, the neural-related symptom cluster, the physical-related symptom cluster, the digestive-related symptom cluster, the respiratory-related symptom cluster, the fever-related symptom cluster, and the sensory-related symptom cluster. The three centrality indices with the highest values were chest tightness (rs = 7.84, rc = 0.013, rb = 6.99), muscle aches (rs = 7.32, rc = 0.013, rb = 2.72), and smell abnormality (rs = 6.56, rc = 0.011, rb = 4.58). Variables including age, gender, income, education, hyperlipidemia, chronic bronchitis, and tumor were associated with the occurrence of these eight symptom clusters. Conclusion: The findings of this study highlight the necessity to explore symptom clusters and symptom networks in order to enhance the effectiveness of symptom management in patients with SARS-CoV-2 infection. Particularly crucial is the evaluation of centrality indices as an integral component of caring for such patients. Early detection of high-risk individuals within each symptom cluster can provide a scientific foundation for developing interventions that will optimize patient prognosis.
