Mean performance metrics of the Recur CDI-IBD obtained from 5-fold cross-validation on the training data

Metric	Mean value	SD (±)
Accuracy	72.75%	2.34%
AUC	0.82	0.03
Sensitivity	0.78	0.09
Specificity	0.75	0.08
Precision	0.72	0.08
Recall	0.71	0.07
F1-score	0.72	0.07

AUC, area under the receiver operating characteristic curve; CDI, Clostridioides difficile infection; IBD, inflammatory bowel disease.

The model demonstrated consistent discrimination between recurrent and nonrecurrent CDI within 60 d.
