The study aims to evaluate the predictive values of each electronic frailty index for the incidence of postoperative infection-related adverse events. This includes the primary outcome of infection events occurring within 30 days and the secondary outcome of the correlations among the five frailty indices.","overall_status":"Completed","phases":[],"study_type":"OBSERVATIONAL","sponsor":"Chinese PLA General Hospital","enrollment":10536,"countries":["China"],"start_date":"2025-03-01","completion_date":"2025-05-06","last_update_date":"2025-05-22","source_url":"https://clinicaltrials.gov/study/NCT06985771","editorial_summary":"A registered study indexed because it matched monitored longevity research terms.
