Fig. 3: Interaction plots of cannabis craving and psychiatric symptoms over time between active and sham treatment.

Interaction plot of cannabis use related symptoms over the course of the trials with values given as estimated marginal means (EMM) ± standard error are used as error bars. EMM were used in interaction plots as a function to visualize the model at the group level (active and sham, each time point), not at the participant or data point level.
