Relative abundance and impact of collaborative interaction within different categories of affiliation associations.

a Each pair is classified into a single category, e.g., the “within institutes” category does not include the “within department” group.b Mean collaboration strength was calculated as the average CLS for all pairs with at least a single co-authored article.c For some of the journals SJR score was not available. Mean IS was calculated only for interactions where (i) collaborative interaction was detected (CLS>0) and (ii) SJR score was available for at least a single journal where a joint publication appeared.* Significant differences were observed between all categories (p- values in a Wilcoxon rank sum test −15).** Significant differences were observed between the “within department” category to the “intra- institutional” and “inter-institutional” categories (p-values in a Wilcoxon rank sum test −16).*** A significant difference was observed between all categories (p-values in a Wilcoxon rank sum test: “inter-institutional” versus “intra- institutional”– 5×10−4; “inter-institutional” versus “within departments”– 6×10−12; “within departments” versus “intra- institutional” –0.02).Relative abundance and impact of collaborative interaction within different categories of affiliation associations.
