Figure 1. Effect of Treatment on CAPS at each Assessment and Extinction Learning across Treatment.

Figure 1

A) CAPS scores at each assessment point across the three conditions. Means are model implied from a mixed effect model that used all participants (n = 156) in the sample. Error bars correspond to 95% confidence intervals for the estimate. B) 95% Confidence bands estimating differences between D-cycloserine (DCS) vs Alprazolam and D-cycloserine vs Placebo at post-treatment. Differences are significant outside of the area defined by the blue lines. The confidence bands indicate that there is a significant difference between the D-cycloserine and Alprazolam conditions when learning was less than −6.29 and greater than 18.99. There is a significant difference between the D-cycloserine and Placebo conditions when learning was less than 4.78 and greater than 23.94.
