"The study did not take into account other potential influencing factors"
A lot of buildings have over 1000ppm of CO2 due to being poorly ventilated, levels where humans start to have noticeable cognitive decline.
Spending so much time at home post COVID I got an indoor air monitor to tell me when to open the windows. 2-3 days of not ventilating will get it over 1000ppm
