SARS-CoV-2 Surface Contamination and Viable Virus in High-Ventilation Single Rooms: Implications for Fomite Transmission.
Article in Juntendo medical journal, 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
Objectives: To evaluate Severe Acute Respiratory Syndrome Coronavirus 2 (SARS-CoV-2) contamination in the rooms of Coronavirus disease 2019 (COVID-19) patients by integrating RNA quantification, viral culture, and post-culture cycle threshold (Ct)-based estimation of infectious titer, and to reassess fomite transmission risk relative to the human infectious dose. Methods: In nine high-ventilation, single-occupancy rooms, adhesive 36 cm Results: Of 134 specimens, 66 (49.3%) were RNA-positive, with a maximum of 8.48 log Conclusions: In high-ventilation rooms, environmental surface contamination was common and viable virus was occasionally present near patients. Estimated titers on some high-touch surfaces exceeded the reported human infectious dose, implying that fomite transmission may remain plausible under specific conditions. Prioritized cleaning/disinfection of high-touch surfaces near patients, along with consistent hand hygiene, are warranted, alongside ventilation/filtration measures.
