Table 3 Summary of the Incidence Rate Ratio (IRR) estimates and 95% lower (L) and upper (U) confidence intervals for MLVA genotype richness across three scales and two production types

From: Variation in Mycobacterium bovis genetic richness suggests that inwards cattle movements are a more important source of infection in beef herds than in dairy herds
