β-Coefficients represent the change in lung function for each 1-unit increase in ln-transformed CO (1 ppm) from a random effects model. See Table 3 legend for expansion of abbreviations.

^aFinal model adjusted for baseline age, height, baseline spirometry, time since baseline spirometry, secondhand smoke, and frequency of temazcal use.
