The Hashimoto Research Group for Comprehensive Research of Gene Mutation-related Rare and Intractable Diseases of the Skin is a contributor to the Project for Research on Intractable Diseases of the Ministry of Health, Labor, and Welfare (MHLW) of Japan. Our research group performs clinical research on 23 rare intractable genetic skin diseases that are classified into eight disease groups. Among the 23 diseases, 17 are mainly studied by our research group, and 6 diseases are studied in collaboration with other research groups.

Immune checkpoint inhibitors (ICIs) are a standard NSCLC treatment. On the other hand, their efficacy remains unclear for ALK-positive NSCLC.

Although there are several methods to test the equality of these predictive values between two medical tests, these approaches separately compare positive and negative predictive values. Therefore, we propose a testing procedure that combines the approximate likelihood ratio test defined by Tang with the non-inferiority test for predictive values.
