Figure 1.

Logit estimates from generalized linear mixed model showing the relationship between the occurrence of body or leg infection between different ages of mosquitoes (age × body part; F = 7.76, df = 2; 3,986, P = 0.0004). The estimated mean probability of infection (model-based estimate; see text for details) and the mean probability of infection (calculated from the data for the appropriate treatment group combined) are plotted for different body parts (body = circle; leg = triangle). The probability of leg infections differs between ages, but body infections are more consistent between ages.
