Hotels as quarantine facilities with airborne virus controls.
Article in Building and environment, 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
During the COVID-19 pandemic, hotels were converted into quarantine facilities, often lacking adequate air-cleaning infrastructure. This study aimed to design effective air-cleaning strategies for controlling viral aerosol transmission, especially inter-zonal transmission, which can undermine the quarantine effectiveness in isolating infected individuals. We developed a validated multi-zone model for an actual quarantine hotel to evaluate performance of air-cleaning strategies. Importantly, we developed the inter-zonal air exchange rate (zACH) index to evaluate the air-cleaning infrastructure effectiveness in reducing inter-zonal transmission of aerosols. The zACH improved significantly from a total of 0.4 1/h of clean air in the baseline strategy without additional air-cleaning to a total of 3.5, 2.8, and 1.7 1/h of clean air for strategies with only GUV fixtures, only HEPA air cleaners, and only air curtains, respectively. We also evaluated the combined air-cleaning strategies that integrated these systems, including air hygiene strategies with fewer devices complementing each other. Our best air hygiene strategy, resulting in the zACH of 8.5 1/h, reduced maximum individual infectious exposure risk below 0.4 % in rooms and below 1.6 % in corridors for a generation rate of 50 quanta/h. Importantly, air-cleaning effectiveness was not linearly proportional to the number of deployed devices, highlighting the importance of balancing performance with installation costs and energy consumption considerations. These findings offer an analytical framework for enhancing infection control in quarantine hotels and provide insights for public health mitigation strategies during pandemics.
