Table 4 Best-fit generalized linear mixed effects model (binomial) of variables and interactions that influenced ovary development

From: Fipronil and ivermectin treatment of cattle reduced the survival and ovarian development of field-collected Anopheles albimanus in a pilot trial conducted in northern Belize

Fixed effects Groups Estimate SE p value Odds ratio (95% CI)
Intercept   1.315 0.369 < 0.0004 3.724 (3.000, 4.448)
Treatment Control (n = 196)
Fipronil (n = 185) − 3.379 0.407 < 0.0001 0.0314 (− 0.764, 0.832)
Ivermectin (n = 91) − 1.776 0.455 0.0001 0.169 (− 0.722, 1.061)
Day after treatment   0.060 0.033 0.07 1.062 (0.998, 1.126)
  1. Model: FullyGravid ~ Treatment + DayAfterTreat + (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. Standard deviation = 0.250)
