Relationship Between Carbon Dioxide Levels and Reported Headaches on the International Space Station
In a recently published article by Law et al,1 there was one error in the Discussion section. In the fourth paragraph on page 482, the threshold average 7-day CO2 concentration to keep the risk of headache below 1% should be 2.5 mmHg, not 1.97 mmHg.
The authors apologize for the error.
