Figure 4 is titled “Loss of PTSD diagnosis for cognitive processing therapy compared with controls.” The figure displays a forest plot reporting the risk difference of loss of PTSD diagnosis stratified by cognitive processing therapy versus waitlist and cognitive processing therapy versus usual care. Data for Figure 4 are presented in Appendix F. This figure is described further in the “Loss of PTSD diagnosis” section as follows: “Our meta-analysis for achieving loss of PTSD diagnosis found that 52 percent more subjects treated with cognitive processing therapy achieved loss of PTSD diagnosis than subjects in waitlist groups (RD, 0.52). This translates to a NNT of 1.9. When also including the study with a usual care comparator, the effect size decreased to 44 percent.”
