Figure 2. Cohort and acquisition support. (A) Internal holdout label counts for CT (n = 16, 8 label-0 and 8 label-1) and MR (n = 17, 4 label-0 and 13 label-1); (B) filename-derived MR acquisition categories: MR_OTHER contains 10 label-1 and no label-0 patients, so its AUROC is not estimable; T1_VIBE_FS contains 3 label-1 and 4 label-0 patients (n = 7). These identifiers are acquisition proxies and do not establish contrast phases. Labels denote study-documented Cs status, not verified infection-negative and infection-positive groups. AUROC: Area under the receiver operating characteristic curve; CT: computed tomography; Cs: Clonorchis sinensis; MR: magnetic resonance; MR_OTHER and T1_VIBE_FS: filename-derived MR acquisition-category identifiers, not verified imaging protocols or contrast phases.
