Probability of common vole (Microtus arvalis) being lipL32-PCR–positive (i.e., probability of vole being infected) as a function of vole weight and different amounts of accumulated rainfall during the 90 d before capture, for voles captured 2011–14 in provinces León, Palencia, Zamora, and Valladolid, northwestern Spain. Points are observed values. Lines are predictions of the best multivariable generalized linear mixed-effects model for the probability of common vole being lipL32-PCR–positive at specific amounts of rainfall (mean=58 mm; maximum=250 mm), which was calculated as follows: 
For the predictions, Tmax was held constant at its mean value (27 C).
