aThe revised item was used to modify the probability of non-AMI given by DLM. For example, if an original probability of STEMI/NSTEMI/non-AMI was 0.220/0.310/0.470, then the prediction was defined as non-AMI according to the largest probability. However, the revised item was used to make DLM become more sensitive, which was used to modify the probability of non-AMI as 0.470-0.450=0.020 as the first situation. Therefore, the new prediction of this case was defined as NSTEMI according to the largest revised probability (0.220/0.310/0.020). bThe sensitivity of STEMI was defined as the percentage of STEMI that was correctly identified as STEMI. cThe sensitivity of NSTEMI was defined as the percentage of NSTEMI that was correctly identified as NSTEMI. dThe specificity is defined as the percentage of non-AMI cases that was correctly identified as non-AMI. |
