REGRESSION, RECURRENCE
LASSO regression analysis included potential risk factors defined in the 2015 ATA guidelines and previous studies. We observed that non-initial treatment may be associated with a higher recurrence rate despite receiving comprehensive therapy including treatment with surgery, RAI, and thyroid-stimulating hormone suppression during clinical practice. Therefore, initial or non-initial treatment was included as a potential risk factor for recurrence. Six predictors were selected from the 15 candidates through LASSO regression, including age >55 years, Selection of significant parameters for clinicopathological variables in the training set.
