1 · What the graph read from it

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.

2 · The registry

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

backgroundThis study aimed to describe yearly laboratory-based detection patterns of respiratory viruses, excluding SARS-CoV-2, among PCR-confirmed positive cases identified through multiplex respiratory polymerase chain reaction (PCR) testing over a six-year period.It focused on the distribution of viruses across different age groups and also differences between immunocompromised and immunocompetent patients.

methodsThis retrospective study included 5,282 PCR-confirmed positive patients identified through respiratory multiplex PCR testing between January 2019 and December 2024. Patient ages ranged from pediatric to adult, with a mean age of 29.4 years; 46.1% were female and 53.9% were male. Nasopharyngeal swab samples were analyzed using real-time multiplex PCR targeting multiple respiratory viruses, including Influenza A/B, human adenovirus, human bocavirus, seasonal coronaviruses, enterovirus, human parechovirus, human rhinovirus, RSV, and human parainfluenza virus types 1–4. Single and multiple viral pathogens were identified within PCR-positive samples.

resultsAmong PCR-confirmed positive patients, 74.6% were immunocompetent whereas 25.4% were immunocompromised. Notably, immunocompromised individuals were significantly older with a higher proportion of males (p < 0.05). A total of 6136 respiratory pathogens were detected. Co-detections occurred in 13.0% of the samples. Human rhinovirus was the most frequently identified pathogen (32.5%), followed by influenza A (13.6%) and RSV (12.5%). Over the study period, variations in laboratory detection numbers were observed. Co-detections were most commonly seen with human rhinovirus, RSV, and human adenovirus. While human rhinovirus and RSV were frequently detected across all age groups, influenza A was more common in adults, whereas human adenovirus and human bocavirus were more frequent in children.

conclusionsAmong PCR-confirmed positive patients, the distribution of respiratory viral pathogens showed significant variations across different age groups and immune status categories. These findings represent laboratory-based detection trends within a healthcare setting rather than population-level incidence.
