A study investigated whether inactive people with knee osteoarthritis raise their physical activity levels more after a PT exercise consultation compared with physician's exercise prescription. 26 people with knee osteoarthritis participated in the study and were randomly assigned to (a)meet with a physician 10 minutes who prescribed an exercise program or (B)meet with a physical therapist (45 minutes) who gave them a home exercise program. All 26 participants were measured before consultation and six weeks later. Participants wore an activity monitor for 3 days at each observation and completed a standardized, validated physical activity questionnaire. Results show significant benefits of physical therapy consultation in terms of activity counts but no significant difference for the questionnaire. The analysis reveals that correlation with the physical therapist can produce a better short-term increase in physical activity than a physician's exercise prescription.

Given the above description, what would be the most reasonable criticism of this study?

Same background This analysis found P = .107 for treatment type; P = .02 for timepoint, and P equals.0316 for the interaction between treatment and time point

What interpretation can be made based on the statements mentioned above?
