Figure 3

Symptom trajectories (GAD-7, PHQ-9, PCL-5 and RPQ) for the four-class solution. Solid, colored lines indicate predicted trajectories, dashed lines the observed values. Shaded areas around lines indicate 95% confidence intervals for predicted values. Gray lines mark cut-off values for categorical classification of outcomes (GAD-7: 5 = mild, 10 = moderate, 15 = severe; PHQ-9: 5 = mild, 10 = moderate, 15 = severe; RPQ: 13 = mild, 25 = moderate, 33 = severe; PCL-5 ≥ 31: PTBS screening). Gray areas mark values above the cut-offs for clinical relevance (GAD-7 ≥ 10; PHQ-9 ≥ 10; PCL-5 ≥ 31; RPQ ≥ 13).
