- Effective Rate of Comprehensive Evaluation [ Time Frame: 52 weeks ]
Evaluate from improvement FEV1.0 (forced expiratory volume in 1 second) and/or Symptoms by Investigator.
Latest time point, at the end of the observation or 1 year after the initiation of treatment, investigator judged and decided "comprehensive evaluation".
"comprehensive evaluation" was classified into 3 category, "improve" "No change+Aggravated" and "Unassessable" by reference to the result of FEV1.0 and symptoms. The effective rate was derived from rate of "Improvement" in total number of analyzed patients
- Forced Expiratory Volume (L) in 1 Second [ Time Frame: Pre treatment and 52 weeks after the treatment ]Difference between Mean of Pre- and each week's forced expiratory volume in 1 second (FEV1) The FEV1 is the volume (Liters) exhaled during the first second of a forced expiratory maneuver started from the level of total lung capacity. FEV1 is by far the most frequently used index for assessing airway obstruction, bronchoconstriction or bronchodilatation
