Patient Characteristics from a COPD Pulmonary Rehabilitation Oxygen Supplementation Trial

Patient data from a double-blind, crossover, randomized controlled trial comparing two oxygen supplementation methods during pulmonary rehabilitation for chronic obstructive pulmonary disease. The dataset includes measurements for six participants, such as 6-minute walk distance, COPD assessment test score, muscle strength, body composition, respiratory function, and joint range of motion. The data was collected by Akihiro Ito and last updated in May 2026.

Use Cases

• Compare the effectiveness of different oxygen supplementation protocols based on patient outcome measures.
• Analyze correlations between muscle parameters and functional capacity in COPD patients undergoing rehabilitation.
• Calculate required sample sizes for future trials based on the reported standardized effect sizes for various endpoints.
• Investigate the suitability of different metrics, like quadriceps muscle power versus CAT score, as primary trial endpoints.

Strengths

• Data originates from a structured, double-blind, crossover, randomized controlled trial design.
• Includes multiple clinical and physiological outcome measures per patient, such as 6MWD, CAT, and muscle strength.
• Reported standardized effect sizes and required sample sizes for five specific parameters provide statistical context.

Limitations

• The dataset is very small, containing data from only six participants.
• Row count and column-level documentation are unknown, requiring manual inspection after download.
• The description indicates the 6MWD and CAT were not appropriate primary endpoints for this small-scale study.
