marginally non-significantP = 0.055
When the ENTOSTAT-TiO 2 -encapsulated virus was considered alone, there was a marginally non-significant decline in performance over the 96 h exposure period (GLM: χ 2 1 = 3.69, P = 0.055), and when the 0 h simulated sunlight-exposure time point was excluded, there was no significant decline in performance (χ 2 1 = 0.31, P = 0.57), suggesting again that the virus is not subject to any further loss of efficacy after the first hour exposure to simulated sunlight.
