A comparison of the effects of exercise in water, on land, or combined (Water and land); on the rehabilitation outcome of patients with intra-articular anterior cruciate ligament reconstructions revealed that less joint effusion was noted after 8 weeks in the water group only. The three intervention groups were compared to a control group for the outcome of joint effusion measured as a continuous variable. What is the appropriate statistical test to compare the girth measurement among the groups?
