Table 1 Summary of estimates of incident rate ratios, using the population averaged negative binomial model to predict network degree (connectivity level) for cluster size ≥ 5 (N = 1517 with number of clusters = 143), 2010–2018: phylogenetic links based on assortative mixing (diagonals) and disassortative mixing (off-diagonals).

  1. Model controls for all study variables listed in Supplemental Table 1S and year of diagnosis. Complete estimated results are provided in Supplemental Table 7S in the online supplemental materials. Asians includes other racial categories of American Indians or Alaskan Natives and Multi-race. Younger is defined as born after 1990, and Older is defined as born in or before 1990. Exchangeable correlation structure and robust variance estimates were used.
