(a): Differences in SpO₂ before and after 6MWT; (b): Differences in HR before and after 6MWT; (c): Differences in RR before and after 6MWT; (d): Differences in VAS before and after 6MWT; (e): Differences in Borg score before and after 6MWT. Box limits indicate the range of the central 50% of the data (the range between the 25th and 75th percentile), with a central line marking the median value. Lines extend from each box to capture the range of the remaining data (maximal-minimal values), with dots placed past the line edges to indicate outliers. Outliers, values they lie on either end of a data, are labeled with a * outside of the range of the whiskers in the box plot. Any data point further than within 1.5 times the interquartile range is considered an outlier. This study included 46 patients before and after intervention.
