In the article “Investigation of the Importance of Applying Various Methods of Calculation in Determining the Blood-Absorbed Dose for Patients with Differentiated Thyroid Carcinoma,” by Al-Shakhrah (J Nucl Med Technol. 2023;51:296–301), a P value of more than 0.05 was erroneously stated as indicating statistical significance and a P value of less than 0.05 as indicating no statistical significance, whereas, in fact, the opposite is true. The author regrets the error.
