Hi Paige, Thank you again for suggesting plausible reasons for the observed wide to extremely wide confidence intervals. However, I would like to seek additional clarification on the possibility of outliers for the categorical variables, in which I have verified based on a descriptive summary statistics analysis that no extraneous category exists. Also, could you perhaps provide some explanations for the observation that certain odds ratio point estimates for exposed group and response group are significant while others for the same exposed group but a different response group are insignificant. I have actually noticed that some of the confidence intervals associated with the significant point estimates are rather narrow, which may indicate relatively larger sample sizes. Nevertheless, I would still like to seek your advice on this observation. Also, could you possibly attempt to provide some explanations as to another observation in which I observed larger point estimates for the "low/medium" response category but smaller point estimates for the "high" response category. I have noticed that some of the larger point estimates correspond with a slightly wider confidence interval, which may be due to relatively smaller sample sizes. Another possible reason may be that relatively greater odds exist in the "low/medium" response category as opposed to the "high" response category for the same independent exposed group. Yet another rather obvious explanation may be that the log odds ratio estimate is simply higher in the "low/medium" response category with the larger odds ratio point estimate compared to that of the "high" response category with the slightly smaller odds ratio point estimate. Again, I would like to seeks your advice on the stated observations. Thank you! Best, Lisa
