- Values represent the mean (± SD). Analysis of variance between the three groups, with total score for bone edema and erosions depicted with magnetic resonance imaging of the hand in three groups of patients with very early rheumatoid arthritis (VERA; disease duration, < 3 months), early rheumatoid arthritis (ERA; disease duration, < 12 months), and established rheumatoid arthritis (ESTRA; disease duration, > 12 months)
- Analysis of variance demonstrated that the three groups were significantly different. Least significant difference test revealed significant difference in bone edema and erosions between VERA and ESTRA.
