From: Changes in peripheral blood lymphocyte subsets during arthritis development in arthralgia patients
Absolute numbers of cells per lymphocyte subset in 73 patients with arthralgia who did not develop arthritis (non-converters), 22 who developed arthritis within a year (early converters) and 18 who developed arthritis after 1 to 5 years (late converters). Black line represents the median of the whole group. Differences between groups were tested using the Kruskal-Wallis test followed by Dunn’s multiple comparison test. N.S. not significant
