Fig 2. Relationship between stromal markers and prognostic outcome in treatment-naive early arthritis tissue.

Expression of (A) FAP (24 self-limiting vs 32 persistent disease), (B) podoplanin (20 self-limiting vs 32 persistent disease), (C) CD248 (10 self-limiting vs 14 persistent disease), (D) CD55 (16 self-limiting vs 18 persistent disease) were measured by pixel counting in synovial regions of interest in baseline samples of early arthritis patients who developed resolving disease (self-limiting) or persistent disease. No significant differences were found. Each dot represents a patient; median bars with interquartile ranges are shown. Significance of the comparisons was determined by the Kruskal-Wallis test.
