The main objectives of the 7-year follow-up of foot pain and OA in a community-dwelling population are: 1. to describe how often foot pain and OA get worse over time 2. to identify which people are going to do well and understand better why some people get worse 3. to examine whether seeing a GP or having treatments affects foot pain and function over time","overall_status":"Completed","phases":[],"study_type":"Observational","sponsor":"Keele University","enrollment":560,"countries":["United Kingdom","England"],"start_date":"2018-10-01","completion_date":"2019-03-31","last_update_date":"2022-02-02","source_url":"https://www.isrctn.com/ISRCTN14731162","editorial_summary":"A registered study indexed because it matched monitored longevity research terms.
