The paper studied how to convert hospital emergency department time-series counts of disease visits into complex networks using a horizontal visibility transformation, and then applied network science structural statistics to compare network topology across disease categories. Across these disease-category networks, the authors report larger clustering coefficients and shorter average shortest path lengths, indicating a stronger small-world effect, with higher average degree specifically for respiratory diseases, which they attribute to greater contagiousness. They also compute the maximum eigenvalue of the network Laplacian and find generally higher values for respiratory diseases than for other categories. A major caveat noted implicitly by the preprint context is that the analysis is presented as a Research Square preprint and has not been peer reviewed. The paper does not explicitly discuss endometriosis or adenomyosis; it was included in the corpus via a keyword match in the upstream search index.

Here, we initially translated hospital emergency data into complex networks through horizontal visualization techniques. Subsequently, we carefully analyzed the topologies of the network structures corresponding to each category of disease by applying the structural statistics approach of network science. Our investigation unveiled that networks constructed by this method exhibit larger clustering coefficients and shorter average shortest paths of the networks, leading to a stronger small-world effect. Moreover, we observed that the average degree of the networks is notably higher for the respiratory diseases, which may be caused by the heightened contagious diseases in the respiratory diseases. Further, by calculating the maximum eigenvalue of the network Laplace matrix, we found that the maximum eigenvalue of the respiratory diseases are generally higher than other categories of diseases. This provides a crucial analytical tool for the proactive prevention of certain specific diseases and more effective response strategies during emergency triage protocols.
