Finding F-0410

“Moreover, it is evident that there are significant associations present with the prevalence of SBS symptoms with indoor CO2 concentrations above 1000 ppm.”

Associations of Indoor Carbon Dioxide Concentration and Symptoms of Sick Building Syndrome in Air-Conditioned Lecture Halls. Page 16. CKB 0357

Structure

Factor: Carbon dioxide (CO₂)
Outcome: Sick building syndrome
Population: university students
Setting: air-conditioned lecture hall, LK
Study design: cross-sectional study of five air-conditioned lecture halls with different occupant densities at a Sri Lankan university: CO2 and relative humidity logged at three positions during two-hour lectures, sick building syndrome questionnaire, ordinal logistic regression per lecture hall (class 4)
Sample: 5 rooms
Caveat: conclusion-level statement; the odds ratios per symptom and lecture hall are printed only in Table 4 (page 28) and are not taken

A Finding records what one published document states, verbatim and with its page. It is not a conclusion of Coridum; see the Claims that build on it.
