Figure 1. Relationship between Bethesda score and age. Bethesda classification was reported as a score from 1 to 6: 1 for non-diagnostic or unsatisfactory, 2 for benign, 3 for atypia of undetermined significance or follicular lesion of undetermined significance, 4 for follicular neoplasm or suspicious for a follicular neoplasm, 5 for suspicious of malignancy, and 6 for malignant.
