If the p-value for the corrected model is 0.053, this is greater than the common significance level of 0.05, so we would not reject the null hypothesis for the main effects of COPD_G2 and Sex. However, if the p-value for the polynomial contrast is 0.03, this is less than 0.05, so we would reject the null hypothesis for the interaction effect between COPD_G2 and Sex
