Table 2 Estimates of bias, B (y, z), and the associated 95% credible regions (95% CR) together with estimates of the 95% limits of agreement for pair-wise comparisons of systolic blood pressure measured by the two observers and the automated machine (m = J, R and S) from two multivariate hierarchical Bayesian models.

From: A multivariate hierarchical Bayesian approach to measuring agreement in repeated measurement method comparison studies
