IL7R and post-traumatic stress disorder: As shown in Figure 2, there was no difference in the number of Tregs (ES = -0.01 [-0.07, 0.06]) but PTSD patients had a higher percentage of CD127-HLA-DR- Tregs (ES = 0.17 [0.05, 0.29]) and a lower percentage of CD127loHLA-DR+ Tregs (E = -0.17 [-0.32, -0.03]).
