Table 2. Unadjusted mean maximum or minimum values and outcome of statistical analyses of mean differences between adjusted means after a day of no treatment, inhalation of formoterol 10 × 4.5 µg, or inhalation of terbutaline 10 × 500 µg via Turbuhaler. Statistically significant differences are in bold.
