Forefoot pathology in rheumatoid arthritis identified with ultrasound may not localise to areas of highest pressure: cohort observations at baseline and twelve months.

Findings showed that there was a significant negative correlation between the presence of US detectable pathology and peak pressure values in the right foot lateral segment at follow up (PCC = -0.412, p = 0.046), but this only demonstrates borderline significance at the 5% level, and care should be taken when inferring from this level of evidence.
