From: CCR6+ Th cell populations distinguish ACPA positive from ACPA negative rheumatoid arthritis
Inverse correlation between proportions of CCR6+CD4+ T cell subpopulations and disease duration in ACPA− patients. Correlation of the percentage of CCR6+CD4+ cells (as percentage of total memory CD4+ T cells) with self-reported disease duration in ACPA+ and ACPA− patients with RA. Pearson correlation test was used to calculate the correlation coefficients (R2) and p-values.
