| Training Set | HFMD-RF against PCIS | 27.9%, P < 0.001 | 30.6%, P < 0.001 | 30.2%, P < 0.001 | 26.8%, P < 0.001 |
| Test Set | HFMD-RF against PCIS | 21.3%, P = 0.017 | 25.2%, P < 0.001 | 24.7%, P < 0.001 | 18.8%, P < 0.001 |
The Chi-square test was used for comparison of Sensitivity, Specificity and Accuracy, and the two-sample t test for AUC between HFMD-RF and PCIS.
