  2. (b): Between-group mean differences and 95% CIs estimated using independent t-tests
  3. (c): The confidence intervals computed assume that the physical health related quality of life variable is normally distributed and includes zero: however, the Wilcoxon signed rank sum test p-value is less than 0.05
