Table 2 Species and location effects of a hurdle model of hourly biting rates

From: Quantifying seasonal and diel variation in Anopheline and Culex human biting rates in Southern Ecuador

  Count model rate ratio Zero model odds ratio
Intercept (An. albimanus) 4.74 (3.05–7.36)*** 4.04 (2.39–6.82)***
Culex spp. 1.38 (0.79–2.42) 3.31 (1.58–6.92)**
An. punctimacula 0.6 (0.31–1.18) 0.65 (0.31–1.36)
Location outdoors 1.55 (1.36–1.75)*** 2.32 (2.03–2.64)***
Culex: outdoors 0.79 (0.66–0.94)** 0.58 (0.48–0.7)***
An. puncti.: outdoors 0.9 (0.71–1.13) 0.8 (0.66–0.97)*
  1. Model coefficients are presented as incidence rate ratios for the count model (which models hourly bites conditional on being bitten), and as odds ratios for the zero model (which models the probability of being bitten). A full table including the species-specific temporally resolved model coefficients is presented in the supplementary materials. Coefficients in this are representative for January at 6 p.m. local time and relative to An. albimanus bite rates. Values in parentheses are 95% confidence intervals. Significance levels are * p < 0.05, ** p < 0.01, *** p < 0.001
