Structure

Factor: Carbon dioxide (CO₂)
Intervention: Ventilation
Population: kindergarten children
Setting: kindergarten classroom, SI
Study design: experimental monitoring of CO2, indoor air temperature and relative humidity in Slovenian kindergarten classrooms of different architectural typologies over 125 days before and during the COVID-19 pandemic (class 4)
Effect: difference 30
Averaging time: average with children present
Caveat: the pandemic ventilation protocols are filed under ventilation; the sentence names the pandemic, not the protocol, as the cause
