Patient recruitment and losses. Patients were excluded if their main diagnosis was not hip OA; if they had malignant, severe organic, or psychiatric diseases; or if they did not undergo surgical intervention, for any reason (death, intervention in other hospital, refusal of the intervention), 1 year after inclusion in the study. Each percentage (in parentheses) is estimated based on the previous frequency except for response rate at 2 years, which was based on the 469 patients who entered the study.
