Figure 2. Symptom development following treatment with NET as a function of trauma load. (a): Bee swarm plots of PTSD symptom severity before therapy and at 4 and 10 months following the end of the treatment. The heat colours represent the levels of traumatic load for each individual, ranging from relatively low levels (represented by white circles) to high levels of traumatic load (represented by red circles). The lines of the plot indicate the median PDS Score (marked in bold) at each measurement point and the interquartile range. (b): Mean PDS symptom scores (standard errors) before as well as 4 and 10 months following the end of the treatment are displayed as a function of trauma load. For a better visualization, the sample has been splitted in tertiles.

Figure 3. Scatterplot of PTSD symptom severity before treatment and at the 10 months follow-up as a function of trauma load. The bold line indicates no change in symptom severity following treatment with NET, while individual data points below and above the dashed line indicate clinically significant improvement (shaded in dark grey) and worsening (shaded in light grey), respectively. The heat colours represent the levels of traumatic load for each individual, ranging from relatively low levels (represented by white circles) to high levels of traumatic load (represented by red circles). To avoid overplotting, individual data points with the same values regarding PTSD symptom severity before and after each other have been plotted next to each other.
