Table 5 Results of assumption tests.
| Variables | Selected test |
|---|---|
| Categorical variable | Chi-square (χ) test with Yate’s correction when sample size >40 and each column have sample >5 in 2×2 tables otherwise Fisher’s exact test in 2×2 tables, For larger tables χ-test with dependence |
| Age (years) | All columns passed the normality test (Normality test p-value >0.1 for all) |
| Postoperative pain intensity (at discharge, 6-months after surgeries, and between discharge and 6-months after surgeries) and hospital stays (days) | All columns failed in the normality test (Normality test p-value <0.05 for all), i.e. non-parametric test |
| Postoperative analgesic dosage | All columns passed the normality test (Normality test p-value >0.1 for all). However, Bartlett statistic (corrected)=6.988. The P value is 0.0304. Bartlett’s test suggests that the differences among the SDs are significant, i.e. non-parametric test |
| Personal satisfaction | one column failed in the normality test (Normality test p-value <0.05 for all), i.e. non-parametric test |
