The 95%-CI for the odds ratio spans from 0.000 to 0.6844, thus an odds ratio of 1.0 is far off and you can reject the null hypothesis, that the values in the contingency table are independent. p = 7.9e-12 means 7.9 × 10 − 12, so very close to zero. Conventionally, the test result is considered 'significant' if p < 0.05. chivalry 2 on gamepass
