Receiver operating characteristic (ROC) curve analysis of the rumen wall thickness for detecting chronic acidosis. The best cut-off value is > 8.2 mm, (area under the ROC curve of 0.88: P < 0.0001; 95% c.i. 0.83 to 0.98; sensitivity 90%; specificity 79%; positive likelihood ratio 4.34; negative likelihood ratio 0.13). criterion: Youden index
