A new medication was developed to manage patients with hepatitis C.

A new medication was developed to manage patients with hepatitis C. 1500 patients were recruited to the study and were divided equally into three groups: one getting the new treatment, one getting sofosbuvir and another getting ribavirin. Patients were followed up for one year to identify those who successfully cleared the infection and those who did not.

Which of the following statistical tests is most appropriate to identify any significant differences in hepatitis C clearance between the medications?
