Indoor Air Quality Conditions and Respiratory Virus Detections in Elementary Schools-Kansas City, Missouri, February-March 2023.
Article in Indoor air, 2025. 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
Background/Objectives: Respiratory viruses circulate year-round and can spread indoors via inhalation of airborne particles. Effective ventilation and filtration may reduce transmission, particularly in school settings where children and staff spend significant time. This study examines the impact of indoor air quality (IAQ) and ventilation in schools on respiratory virus detection. Methods: During February 27 to March 30, 2023, we assessed the relationship between IAQ and respiratory viruses in two Kansas City, Missouri, elementary schools by collecting bioaerosol samples, student and staff nasal swabs, and monitoring IAQ across 10 rooms (six classrooms, two common spaces, and two nurses' offices). We calculated air changes per hour ( Results: We collected 173 nasal swabs from 100 participants and 30 bioaerosol samples from 10 rooms. Participants were mostly female (68%) and white (60%). Viruses were detected in 90% of bioaerosol and 35% of nasal samples. Four classrooms and both common spaces had the same virus detected in bioaerosol and nasal swab samples. None of the spaces met the CDC recommended Conclusions: Viral presence was found in bioaerosol and nasal samples with some overlap in concurrently collected samples. Findings suggest a possible connection between high CO
