Yоu wаnt tо design а Rаndоmized Control Trial to evaluate the treatment effectiveness of VMO training during closed kinetic chain exercises for patients with patella-femoral pain. Three groups will be compared: a control group (no treatment), a group with general exercise programs and a group with a specific program designed based on closed kinetic chain exercises for VMO.

What statistical analysis will help you to control for the presence of this confounding variable?
