# Odds ratios with 95% confidence interval

Be aware of that the graph neither reflect any scientific researches nor convey any scientific knowledge. We are focusing on how teachnically make the graph. All the titles and numerical values are purely hypothetical.

The technics can be applied to any regression coefficient such as risk ratio, prevalence ratio, hazard ratio etc.

You can view and download the Stata do.file to reproduce the exactly same graph.
