Table 5 Mutual independence testing results among gender, intervention and survival
Hypothesis (H0) | Chi-square statistic | Degree of freedom | Critical value | Result |
|---|---|---|---|---|
Gender, intervention and outcome are mutual independent | 25.5 | 7 | 14.1 | p < 0.05, reject H0 |
Outcome is independent of gender and intervention | 25.5 | 5 | 11.1 | p < 0.05, reject H0 |
Gender is independent of intervention and outcome | 8.4 | 5 | 11.1 | p > 0.05, accept H0 |
Intervention is independent of gender and outcome | 21.7 | 6 | 12.6 | p < 0.05, reject H0 |
