The groups Oral disease, Obesity, Oral disease & Obesity are compared with the Healthy group
The bivariate analyses integrate the school and investigator effects
For the explanatory variables, each category is compared with a reference category indicated with a R
Proportions (%) are calculated per line for the different COGHI groups and per column for the total
