Table 4.

This table shows AUROC, NPV, and PPV values along with their confidence intervals measured for each individual latent variable for 100 iterations (each corresponding to a different division of training and validation datasets).

Second latent variable (T2WI)	0.79	0.72–0.85	0.84	0.78–0.90	0.71	0.68–0.74
Third latent variable (T2WI)	0.76	0.75–0.80	0.72	0.67 0.74	0.72	0.70–0.74
Fourth latent variable (T2WI)	0.66	0.64–0.68	0.58	0.57–0.60	0.69	0.65–0.73
First latent variable (ADC)	0.91	0.90–0.92	0.88	0.85–0.90	0.82	0.80–0.84
