The research center of gravity is Medicine as the leading field (33% of slots across 25 PIs; 25 labels), Molecular Biology as the leading subfield (19% of slots across 18 PIs; 18 labels), and Gut microbiota and health as the leading topic (5% of slots across 5 PIs; 5 labels). Overall the pattern is balanced: there is enough structure to identify active groups, while the field mix still leaves room for multiple research identities. The most prominent PIs by weighted works are Lam C. Tsoi (10 weighted works; Hidradenitis Suppurativa and Treatments, Autoimmune and Inflammatory Disorders); Robert P. Dickson (8 weighted works; Gut microbiota and health, Pediatric health and respiratory diseases). The strongest pairings are Evan S. Snitkin and Kyle J. Gontjes (3 shared works, weight 1.6). The strongest breakdown groups are group 1 with 10 PIs, 10 internal connections, weight 7.9, around Infectious Diseases, Molecular Biology, Immunology, led by Lam C. Tsoi, Teresa R. O’Meara, T.
