 Various optical measures for finger joints that received a US score of 3 (affected by RA) and 0 (unaffected by RA)

Score (1, …,5)Min(μs) (cm−1)Min(μa) (cm−1)Max(μs) (cm−1)Max(μa) (cm−1)Min(μs)/Max(μs)Min(μa)/Max(μa)
Results are shown as mean values (standard errors).
The entries in bold identify cases in which the difference between the mean values found for the affected and unaffected joints is significant (p<0.05).
