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
Introduction: Respiratory viral infections vary in their clinical presentation, treatment approaches and outcomes. Therefore, accurate, timely and cost-effective detection of key pathogens, particularly SARS-CoV-2 and influenza A/B, which are among the most common causes of respiratory infections, is crucial. This study aimed to identify the presence of COVID-19 and influenza A/B, as well as their co-occurrence, in hospitalized pediatric patients presenting with respiratory viral infections symptoms. Materials & Methods: Nasopharyngeal specimens were collected from pediatric patients admitted to Mofid Children's Hospital in Tehran, Iran who exhibited symptoms of viral respiratory infections. Detection of SARS-CoV-2 and influenza A/B was achieved using multiplex real-time polymerase chain reaction (PCR) following total RNA extraction of samples. Data regarding symptoms and other pertinent information about the patients were collected via a questionnaire. Results: A total of 2,353 hospitalized children in this study, ranging from under one year old to 18 years old. Of these 43% were female and 57% male. Fever was the most commonly reported symptom. The results of the multiplex real-time PCR were positive in 8% of cases, including 55% for COVID-19, 8.5% forinfluenza A, 26% for influenza B, and 10.5% for co-infections. Conclusion: The results of this study suggest a decline in seasonal influenza incidence compared to previous years, potentially due to the improved personal protection measures during to the COVID-19 pandemic. On the other hand, the presence of co-infection in this study is important and this co-infection should be considered in treatment and diagnostic systems in respiratory infection by physicians. Importantly, the presence of co-infections highlights the need for clinicians to consider dual pathogen involvement in diagnosis and treatment strategies for respiratory infections.
