a. Contour plots of the combined effect of evaporation and time lags on the relative risk of transmission of human brucellosis. c. Effects of specific evaporations and time lags on the relative risk of transmission of human brucellosis. The red lines are the mean relative risks, and the gray lines are 95% CI. c. Effect of specific evaporations and time lags on the cumulative risk of transmission of human brucellosis. The red lines are the mean relative risks, and the gray areas are 95% CI
