Figure 4. Kaplan-Meier overall survival analysis using anti-thyroid peroxidase (TPO) titers.
Patients were dichotomized based upon anti-TPO levels greater than median (10.0 IU/mL) or ≤ median at ( a) baseline and ( b) pre-cycle 3. P-values are unadjusted and calculated using the Wald test. B, baseline; C3, pre-cycle 3; CI, confidence interval; HR, hazard ratio.
