Table 3 Model 1 ‘Physiological status’ and ‘region’ as potential risk factors for reactivity in the comparative tuberculin test on positive herds with ≥5 tested animals (4,776 observations within 344 positive herds) and animals tested, number and proportion of positive reactors in all positive farms (5269 observation). Estimated variance for herd: 1.118 on the logit scale

From: Prevalence and risk factors of bovine tuberculosis in dairy cattle in Eritrea
