Fig. 4 — Regularized partial network analysis of the top features

Note. The thickness of an edge reflects the magnitude of the association. Green full lines represent positive regularized partial correlations. Yellow nodes represent variables related to childhood maltreatment experiences. Green nodes represent variables related to addiction severity, history of treatments and drug use behavior, psychiatric problems (difficulties) score and family/social-related problems score. Purple nodes represent variables related to cocaine withdrawal. The hyperparameter γ was set in 0.5, favoring a simpler model containing fewer edges.
