Finding F-0417

“For these seven scales, compared with mean raw scores at 600 ppm CO2, mean raw scores at 1,000 ppm CO2 were 11–23% lower, and at 2,500 ppm CO2 were 44–94% lower.”

Structure

Factor: Carbon dioxide (CO₂)
Outcome: Cognitive performance
Population: adult volunteers
Setting: exposure chamber (office-like), US
Study design: blinded controlled exposure study with balanced crossover order: 22 participants in six groups exposed in an office-like chamber to CO2 at 600, 1,000 and 2,500 ppm in three 2.5-hour sessions on one day, ventilation rate and temperature constant, computer-based Strategic Management Simulation test of decision-making performance analysed with analysis of variance (class 3)
Effect: difference 23
Sample: 22 participants
Caveat: the sentence gives a range across seven scales; the two ends are recorded as two rows; decision-making performance filed under cognitive-performance

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.
