The 6 hour peak change from baseline is the maximum of the post-dose change values through 6 hours at each visit.
Number of Participants With Potentially Clinically Significant Heart Rate
Number of subjects with a heart rate that was lower/higher than a set limit and increased/decreased from set baseline limit in beats per minute (bpm)
Ipratropium Bromide Metered Dose Inhaler (MDI) Usage: Days Used Per Week
Supplemental medication usage is recorded throughout the study. MDI stands for metered dose inhaler.
Ipratropium Bromide Metered Dose Inhaler (MDI) Usage: Number of Actuations Per Day
Supplemental medication usage during the study. MDI stands for metered dose inhaler. An actuation is one depression of the device that releases medication.
Racemic Albuterol or Levalbuterol Metered Dose Inhaler (MDI) Usage: Days Used Per Week
Rescue medication usage during the study. MDI stands for metered dose inhaler.
Racemic Albuterol or Levalbuterol Metered Dose Inhaler (MDI) Usage: Number of Actuations Per Day
Rescue medication usage during the study. MDI stands for metered dose inhaler. An actuation is one depression of the device that releases medication.
Time-Normalized Area Under the Curve (nAUC) From 0 to 6 Hrs for Forced Expiratory Volume in One Second (FEV1) Changes From Baseline
Area under the change from baseline curve from 0 to 6 hours. Time-normalized AUC (0-6 hrs) was derived using the linear trapezoidal method.
Transitional (Relative Change in) Dyspnea Index
The transitional focal score (-9 to 9) is the sum of relative change from baseline for the Functional Impairment, Magnitude of Task, and Magnitude of Effort scores (each -3 to 3 scale). A Transitional Dyspnea Index score of -9 represents a maximum degradation of all three tests; a score of 9 represents a maximum improvement of all three tests.
Number of Participants With an Improved Transitional Dyspnea Index
The number of participants with a transitional focal score (range -9 to 9) of >=1 improvement. Transitional focal score compares current health against baseline for the Functional Impairment, Magnitude of Task, and Magnitude of Effort scores. A score of -9 is maximum worsening and 9 is maximum improvement.
Forced Expiratory Volume in One Second (FEV1) Changes From Baseline for 24 Hour Post Dose Timepoint (Trough)
The 24 hour trough is the FEV1 value obtained 24 hours post first dose. This value is compared to the baseline FEV1 value.
Subject Global Evaluations Change From Baseline
The global evaluation is a COPD symptoms rating ranging from 1 to 7, with 1=much better and 7=much worse. Ratings were assessed relative to the subject's initial entry into the study.
Investigator Global Evaluations Change From Baseline
The global evaluation is a COPD symptoms rating ranging from 1 to 7, with 1 = much better and 7 = much worse. Ratings were assessed relative to the subject's initial entry into the study.
BODE Index
The BODE index (0=relative health and 10=severe chronic obstructive pulmonary disease) is a multi-dimension COPD grading system that incorporates body-mass index (B), degree of airflow obstruction (O), dyspnea (D), and exercise capacity (E) as measured by the 6-minute walk test. Scores were derived using pre-dose assessments from each visit.
6-Minute Walk: Change From Baseline in the Distance Walked in 6 Minutes
Mean change from baseline in distance walked (meters)
Mean Change From Baseline in St. George's Respiratory Questionnaire
Scores are expressed as a mean change from baseline of overall impairment (total score). The questionnaire has a scale of 100 which represents worst possible health status to 0 which indicates best possible health status.
Number of Participants With a >=4 Unit Improvement on the St. George's Respiratory Questionnaire
Scores are expressed as the number of participants with >= 4 unit improvement in overall impairment (total score), where 100 represents worst possible health status and 0 indicates best possible health status.
Modified Medical Research Council Dyspnea Questionaire
Scores range from 0 to 4, with a score of 4 indicating that a subject is too breathless to leave the house or becomes breathless when dressing or undressing. The highest numbered question to which the subject answered 'Yes' is the Dyspnea Scale Score.
Percent (%) of Participants With an Improved Transitional Dyspnea Index
The percentage of participants with a transitional focal score (range -9 to 9) of >=1 improvement. Transitional focal score is the sum of the Functional Impairment, Magnitude of Task, and Magnitude of Effort scores. A score of -9 is maximum worsening and 9 is maximum improvement.
Percent (%) of Participants With a >=4 Unit Improvement in the St. George's Respiratory Questionaire
Percent of participants with a >=4 unit improvement in the overall impairment (total score) of the St. George's Respiratory Questionaire. This questionaire uses a 100 - 0 scale, where 100 represents the worst possible health status and 0 indicates the best possible health status.
Mean Values for the 6-Minute Walk Test: Distance Walked in Meters
This test measures the participants' level of fitness. It is a measure of the distance the participant can walk in 6 minutes.
