Best-fit generalized mixed effects model (binomial) of variables that influenced blood digestion
| Fixed effects | Groups | Estimate | SE | p-value | Odds ratio (95% CI) |
|---|---|---|---|---|---|
| Intercept | 2.181 | 0.486 | < 0.0001 | 8.852 (7.900, 9.804) | |
| Treatment | Control (n = 196) | – | – | – | – |
| Fipronil (n = 185) | 1.595 | 1.100 | 0.147 | 3.781 (2.772, 7.085) | |
| Ivermectin (n = 91) | − 1.661 | 0.534 | 0.0019 | 0.201 (− 0.856, 1.236) | |
| Day after treatment | 0.114 | 0.053 | 0.0318 | 1.121 (1.017, 1.225) |
Model: BMneg ~ Treatment + DayAfterTreatment + (1|CowID) where the fixed effects were ‘Treatment’ (n = total number of mosquitoes dissected per treatment group) and ‘Day After Treatment’. The random effect was ‘CowID’ (i.e., the six individual heifers)
