Cut-offs of Altmetric score (AS) needed (bold) to reach the top 25% of cited articles that coincide with the provided sensitivity in the table (italics), while keeping a specificity of ~80% for the respective articles. Every year post-publication was calculated (first year, second year, third year, fourth year) in a receiver operating curve analyses. AUC: area under the curve, outlined for each model. 95% CI: 95% CI; +LR: positive likelihood ratio, -LR: negative likelihood ratio
