Abbreviations: OR = odds ratio; 95%CI = 95% confidence intervals; pvalue = pvalue for the regression coefficient (exponentiated and presented as odds ratio); lnLAP = natural logarithm of the lipid accumulation product; SLD = suspected liver disease; pBrant = pvalue associated with the Brant test of proportional odds; pHL = pvalue associated with the Hosmer Lemeshow statistics of the 2 binary models underlying the proportionalodds model; AUROC = area under the ROC curve; BIC = Bayesian information criterion.
