The association between variables requires correlation or association measures, in this case since a drop in the prevalence of obesity was determined and it could be due to factors such as diet, schooling (university or non-university), the use of Ozempic. Then a case-control study must be developed, where people who have reduced their body weight and others who have not are evaluated, then the variables DIET, SCHOOLING AND USE OF Ozempic are controlled in both groups and according to the OR value and taking into account the confidence index and the alpha error, the association or not between these variables and weight loss can be determined. It is as easy as that.
