The key features mimic those of the model that lacks graph features; however, it's been enriched with graph metrics. Additionally, the relevance of each feature sees a significant boost compared to their counterparts in the base model. This suggests that including fewer graph features can augment the model's accuracy and insight, offering a greater yield than a wide range of features used in a model without graph elements
