Viral Etiologies of Acute Respiratory Illness in Older Adults and of Congestive Heart Failure and Chronic Obstructive Pulmonary Disease Exacerbations Requiring Hospitalization During 2 Prepandemic Respiratory Seasons.
Article in Open forum infectious diseases, 2025. The graph could read no effect estimate from its abstract, so it casts no vote on the map. Cited by 2 papers.
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
Background: In adults, the infectious etiologies of acute respiratory illnesses (ARIs) and of exacerbations of cardiopulmonary diseases requiring hospitalization are incompletely understood. Methods: We conducted a prospective surveillance study of older adults hospitalized with acute respiratory illness (ARI) and adults of any age hospitalized with exacerbations of congestive heart failure (CHF) or chronic obstructive pulmonary disease (COPD) at 2 urban hospitals in Atlanta, Georgia, during the 2018-2019 and 2019-2020 respiratory seasons along with contemporaneous healthy controls. All participants had nasopharyngeal and oropharyngeal swabs collected and tested for common viral and bacterial etiologies using a BioFire multiplexed respiratory panel. A subset of patients had paired serological testing for respiratory syncytial virus (RSV), and standard-of-care microbiologic testing results were included when available. Demographics, clinical characteristics, and outcomes were determined through a combination of participant interview and medical record abstraction for hospitalized participants. Results: A total of 1558 participants were enrolled and included in the analysis. Overall, 757 participants (48.6%) were hospitalized for ARI, 490 (31.5%) for CHF exacerbation, and 311 (20.0%) for COPD exacerbation. At least 1 pathogen was detected in 476 (30.6%) participants, most commonly rhinovirus/enterovirus (127/1558 [8.2%]), influenza (119/1558 [7.6%]), and RSV (92/1558 [5.9%]). Although bacterial and fungal infections were uncommon, these were associated with severe clinical outcomes, including duration of hospitalization and mechanical ventilation. Conclusions: Respiratory viruses contributed substantially to hospitalization for ARI and cardiopulmonary exacerbations among our cohort of high-risk adults, underscoring the need for effective therapeutic and preventive interventions in this vulnerable population.
