The relative risk ratio is represented by RRR, the SE by the significance by p value. The level of significance was set at p<0.05 and bold indicates significant results.
*Note: 0=normal to normal (referent), 1=normal to overweight/obese, 2=overweight/obese to overweight/obese, 3=overweight/obese to normal.
