Antioxidant therapy significantly reduces disease-related symptoms for patients with knee osteoarthritis.
The approach for this systematic review and meta-analysis was based on thorough literature analysis with no time or language restrictions from prominent databases including PubMed, International Scientific Indexing, and Scopus. The search was focused on the connections between "osteoarthritis" and "antioxidants". This study considered pain as the primary outcome while also analyzing the symptoms, functions of knee osteoarthritis, and quality of life. All these variables were measured using the corresponding instrument from existing studies. Only randomized controlled trials with a placebo control or other medical therapeutic interventions were included. Publication bias was evaluated using Begg's funnel plot and Egger's regression test, and results were validated using the trim-and-fill test.
From the initial 7,698 papers, information was obtained from 31 selected documents. Results showed that antioxidant therapy significantly affected the symptoms of patients with knee osteoarthritis, as validated using the Visual Analog Scale. However, there was no notable difference observed in the combined score, difficulty score, pain score, and stiffness score as reported by the Western Ontario and McMaster Universities Osteoarthritis Index.
