Time represents the rate of change in FEV<sub>1</sub> in never smokers and the smoking-by-time interaction term represents the effects of the other three smoking patterns on the rate of change in FEV<sub>1</sub>, compared with never smokers. Smoking categories are defined as persistent (smoke throughout follow-up), intermittent (stop and/or start smoking during follow-up) and former (smoke only prior to start of follow-up).</p>†<p>Effect estimates in smoking categories are added to estimates in never smokers to compute the actual rate of change in each group (for example, in ARIC, the point estimate of the rate of change in FEV<sub>1</sub> in persistent smokers was −14.0 − 12.4  =  −26.4 mL/year).</p
