The confounding can be controlled by restriction by study design (for example, restricted age range as 2-6 years), matching (use of constraints in the selection of the comparison group so that the study and comparison group have similar distribution with regard to potential confounder), stratification in the analysis without matching (involves restriction of the analysis to narrow ranges of the extraneous variable) and mathematical modelling in the analysis (use of advanced statistical methods of analysis such as multiple linear regression and logistic regression). It keeps the characteristics of the participants (for example, age, weight or physical status) as similar as possible across the study groups.
