Triple Viral Respiratory Co-Infection With Respiratory Syncytial Virus (RSV), Human Metapneumovirus (HMPV), and Influenza A (H1N1) Leading to Acute Respiratory Distress Syndrome (ARDS) in an Infant: A Case Report.
Article in Cureus, 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
Viral respiratory infections are a major cause of morbidity in pediatrics. We report a rare case of triple infection with respiratory syncytial virus (RSV), human metapneumovirus (HMPV), and influenza A (H1N1) in a previously healthy nine-month-old infant, complicated by acute respiratory distress syndrome (ARDS). The patient presented with severe respiratory distress, elevated inflammatory markers, and bilateral alveolar infiltrates, requiring non-invasive ventilation. A point-of-care multiplex PCR using the BioFire® Respiratory Panel 2.1 plus (RP2.1plus; bioMérieux, Marcy-l'Étoile, France) detected all three viruses. Confirmatory testing with the Xpert® Xpress Flu/RSV quadriplex PCR (Cepheid, Sunnyvale, CA) showed low cycle threshold (Ct) values for RSV and H1N1. Despite antiviral treatment, the patient's condition worsened, requiring invasive mechanical ventilation for 60 days. This case highlights the rarity and diagnostic complexity of triple respiratory viral co-infection and underscores the role of multiplex PCR in rapid pathogen detection. The interpretation of Ct values may provide additional diagnostic information but should be considered within the clinical context.
