From: Where’s the risk? Landscape epidemiology of gastrointestinal parasitism in Alberta beef cattle
Model predicted spatial and temporal variation in risk of GIN transmission in Alberta bovine calves (2008–2010). Distribution of expected risk of nematode transmission calculated for each year using Bayesian inference to construct hierarchical binary response logistic regression models for ODR in cattle sampled at auction markets in southern Alberta from 2008 to 2010. Low, Moderate and High risk are differentiated according to mean regional optical density ratio values of <0.3, 0.3-0.5, and >0.5 respectively for cattle serum
