Note: Percentage differences and 95% confidence intervals are plotted for groups of boys and girls with differing levels of smoking as compared with those of identical age and log height who had never smoked, with adjustment for age, log height at each age, residence, parental education, and maternal smoking status. “Never” denotes never having smoked; “Former,” formerly having smoked; “Light,” 1/2–4 cigarettes/day; “Medium,” 5–14 cigarettes/day; and “Heavy,” ≥15 cigarettes/day. FEF25–75 = forced expiratory flow between 25% and 75% of FVC; FEV1 = forced expiratory volume in 1 second; and FVC = forced vital capacity.
