  1. n Animals with complete record for respective model
  2. aOnly positive samples with Trichinella species were included in the model
  3. bSingle infection means infection with any one of the listed species Trichinella T6, T. nativa, T. chanchalensis, or T spiralis; co-infection means co-infection with either Trichinella T6 and T. nativa, Trichinella T6 and T. chanchalensis, or T. nativa and T. chanchalensis
