carbon monoxide has been researched along with Sensitivity and Specificity in 172 studies
Carbon Monoxide: Carbon monoxide (CO). A poisonous colorless, odorless, tasteless gas. It combines with hemoglobin to form carboxyhemoglobin, which has no oxygen carrying capacity. The resultant oxygen deprivation causes headache, dizziness, decreased pulse and respiratory rates, unconsciousness, and death. (From Merck Index, 11th ed)
carbon monoxide : A one-carbon compound in which the carbon is joined only to a single oxygen. It is a colourless, odourless, tasteless, toxic gas.
Sensitivity and Specificity: Binary classification measures to assess test results. Sensitivity or recall rate is the proportion of true positives. Specificity is the probability of correctly determining the absence of a condition. (From Last, Dictionary of Epidemiology, 2d ed)

"Study team generates the smoke free days outcome by counting days where no cigarettes and no other forms of combusted tobacco products are used. Days where participants use no nicotine products and days where participants only vape are smoke free. Percentage of smoke free days = the number days that participants reported smoking 0 cigarettes (0 study cigarettes and 0 non-study cigarettes) divided by the total number of days between their randomization and Week 12 visits. Due to the distribution of the data, statisticians grouped participants according to whether they had 0 smoke-free days or more than 0 smoke free days during the study." (NCT03185546)
