A hospital is conducting a study to compare two different surgical techniques for treating knee osteoarthritis. Patients are randomly assigned to receive either Technique A or Technique B , and their pain levels and joint function are assessed at 6 months and 1 year post-surgery. The study is double-blinded, meaning neither the patients nor the surgeons performing follow-up assessments know which technique was used. What is the primary advantage of this study design? a. It ensures that only the most skilled surgeons perform the surgeries b. It allows researchers to establish causality between the surgical technique and patient outcomes c. It eliminates all possible biases in the study d. It minimizes the effect of genetic differences among patients
