  1. The numbers of Lu et al. are directly obtained from Ref.21, which reported its estimation results of 37 states over three flu seasons: 2014–2017. For fair comparison, the result of ARGOX is restricted to the same 37 states and the same time period to match Ref.21. The method with best performance for each metric in each period is highlighted in boldface.
