*3.5. GPR120 Serum Concentration Variability*

To further determine the independent predictors of GPR120 serum concentration using a multiple regression model, the following explanatory variables were used: age, BMI, and serum concentration of ALA, AA, EPA, and DHA. In the patient group, there were no relationships between GPR120 concentration and other variables (*p* > 0.05). In the HC group, ALA and DHA serum concentration were independently associated with GPR120 (*p* < 0.05) in a model adjusted for EPA concentration. The model explained 38.59% of GPR120 serum concentration variability. The estimated relationship was not statistically significant after Bonferroni correction (*p* > 0.0167).
