Comparison of subpopulations of peripheral blood T and B cells in RA patients after adjustment with propensity score weighting. Inverse probability weighting adjustments with propensity scores were performed to control for biases caused by the imbalance of potential confounding factors in comparison of subpopulation in T cells (A) and B cells (B) of PBMC collected from RA patients in two hospitals. The graph shows the mean difference with 95% confidence intervals for each subpopulation after IPW adjustment. Positive or negative numbers represent increase or decrease of the subpopulations in the patients in Karuizawa, respectively. Statistical significance was defined as *P < 0.05, **P < 0.01, ***P < 0.001, and ****P < 0.0001.
