Imb spss statistic for windows version 24

Descriptive statistics were used to present the characteristics of the participants of the pulmonary rehabilitation program, and baseline outcome variables. Percentages were used for categorical variables and means (standard deviations (SDs)) for continuous variables. Paired t-tests were used to explore mean differences in exercise capacity, self-efficacy and health-related quality of life before and after participation in the RP program. Cohen’s d was used to calculate effect size of the intervention (small (0.2), moderate (0.5), large (0.8)). Spearman correlations were used to examine relationships between changes in 6MWT, dyspnea, and self-efficacy with change in health-related quality of life after the pulmonary rehabilitation program. Statistical significance was set at p-values ≤ 0.05. All analyses were performed using IMB SPSS Statistic for Windows, version 24.0 (IBM Corp., Armonk, NY, USA).

The baseline characteristics and outcome variables of the participants included in the PR program were presented by descriptive statistics. Normality was examined by the Kolmogorov–Smirnov test. Means (standard deviations (SDs)) were used for continuous variables while percentages were used for categorical variables. We performed paired t-tests to examine mean differences in self-efficacy, exercise tolerance, nutrition assessment as well as mental health status before and after the PR program. All statistical analyses were performed using IMB SPSS Statistic for Windows, version 24.0 (IBM Corp., Armonk, NY) and P values ≤ .05 was considered statistical significance.
