| aThe sample median (25th and 75th percentile) is given for numerical variables. bSt. George Respiratory Questionnaire (SGRQ) smaller index score indicates less chronic airflow limitations. cShort Form-12 (SF-12) scores have a mean of 50 and standard deviation of 10 in the general U.S. population; higher scores correspond to higher health levels. dSF-12 data was incomplete for one patient at baseline. eP-values refer to changes since baseline and result from Wilcoxon signed rank tests. |
