The distributions of CAP scores among the most influential accounts, by PageRank (left), h-index (middle), and retweet count (right), in the retweet network of the Apolitical and Divisive Political discussions. The violin plots, and the quartile lines within each violin plot, show the distribution of CAP scores for users among the top decile of accounts with respect to the corresponding measure, in each topic within each category of discussion. The two-sided Kolmogorov–Smirnov test reveals statistically significant difference between each pair of distributions at significance level \(p < 0.001\) for PageRank and retweet count, but this difference is not statistically significant for h-index. The left half of the violin plot (Apolitical) contains 790 CAP scores and the right half (Divisive Political) contains 7385 CAP scores.
