Table 7 Model selection based on Akaike information criteria (AIC) of the effect of bacterial dose on virulence

From: Coinfection outcome in an opportunistic pathogen depends on the inter-strain interactions

Model AIC df P
Strain + Dose + Strain: Dose 410.50 6  
Strain + Dose 448.86 4 <0.001
Dose 489.20 2 <0.001
  1. + describes the main effects and colon the interactions
  2. The best fit model estimating mortality risk of the zebra fish within time is underlined. P value indicates the significance of the term removed from the higher model
