Fig. 2From: Thyroid dysfunction in Chinese nasopharyngeal carcinoma after anti-PD-1 therapy and its association with treatment responseThyroid-stimulating hormone kinetics and free T4 kinetics during treatment in patients in the immunotherapy group with different patterns of thyroid function. A Median TSH during treatment in patients in the immunotherapy group with normal thyroid function, hypothyroidism, hyperthyroidism, and biphasic thyroid dysfunction. Dashed lines represent normal TSH ranges (0.27–4.2 μIU/L). B Median FT4 during treatment in patients in the immunotherapy group with normal thyroid function, hypothyroidism, hyperthyroidism, and biphasic thyroid dysfunction. Dashed lines represent normal FT4 ranges (12–22 pmol/L). TSH, thyroid-stimulating hormone; FT4, free T4Back to article page
