  1. UPAPS is Unesp-Botucatu Pig Composite Acute Pain Scale; # is total sum; & is probability of needing analgesia based on the algorithm; AUC is area under the curve; comparison between two AUCs was conducted with the DeLong test; the optimal cut-off point was determined by the Youden index (Specificity + Sensitivity – 1).
