Extended Data Fig. 9: Prediction of mental health care services in 2022 by deciles of predicted change in PTSD symptoms.

Circles denote linear regression coefficients predicting log transformed expenditures (a) and relative risk ratios from robust quasi-Poisson regressions (b,c), adjusted for the effects of demographic factors and baseline PTSD symptom severity (Supplementary Tables 15–17). Vertical bars denote 95% confidence intervals calculated using heteroscedasticity-consistent (HC1) standard errors.
