Pasw statistics version 20

Descriptive statistics or frequency distributions such as mean, standard deviation, median, and percentage were presented for continuous or categorical variables. A χ² test or Fisher exact test was used for categorical variables. For comparisons of cost according to disease status, as the values did not have a normal distribution, an analysis of variance was used after converting the values to a log scale and the Mann–Whitney test or Kruskal–Wallis test was additionally used. All statistical analyses were 2-sided and performed using PASW Statistics version 20.0 (SPSS Inc, Chicago, IL). P < 0.05 was considered to be statistically significant.

The primary end point was to identify predictors of clinical failure of C/T therapy.
Continuous variables were compared using the Student t test and Mann-Whitney U test for normally and non–normally distributed variables, respectively. The χ ² test or Fisher exact test was used to compare categorical variables. All pretreatment variables identified during univariate analysis were tested using logistic regression analysis to identify risk factors associated with clinical failure. In a multivariate analysis, the model was tested using a backward stepwise selection and P < .05 for all variables in order to determine the effects of all anamnestic, clinical, and therapeutic variables on clinical success or failure of C/T therapy. Empiric and definitive therapy were adjusted for confounders (definitive and empiric regimens, respectively). All tests of statistical significance were 2-tailed. Differences were considered statistically significant at a P value of <.05. Statistical analysis was performed with the software package PASW Statistics, version 20.0 (SPSS Inc., Chicago, IL, USA).

Microsoft Office Excel 2017 and PASW Statistics version 20.0 (SPSS, IBM Inc., BM Corp., Armonk, NY) were used for data processing and statistical analyses, respectively. All the variable results are presented as mean ± SD and 95% confidence interval (CI). Linear regression analyses were conducted to calculate the slopes and intercepts describing the relationship between gross EE and repetition frequency for each BWRE-slow. Paired t-tests were conducted to compare the slope, intercept, and resting EE for each exercise. In addition, we conducted paired t-tests to compare the mean EEs computed for the repetition frequency of 10 repetitions·min⁻¹ using 2 different calculation methods. The statistical significance level was set at 0.05.
