Testing for noninferiority and equivalence between an experimental therapy and a standard therapy in terms of the ratio of binomial proportions is considered. New tests based on the Fieller-Hinkley distribution of the ratio of random variables are proposed. Restricted maximum likelihood estimates of the null variances are used to derive the tests. Sample size determination is discussed. The proposed test procedure is extended to multiple tables. The tests are applied to numerical examples.

Liver cancer poses a global health challenge with limited therapeutic options. Notably, the limited success of current therapies in patients with primary liver cancers (PLCs) may be attributed to the high heterogeneity of both hepatocellular carcinoma (HCCs) and intrahepatic cholangiocarcinoma (iCCAs). This heterogeneity evolves over time as tumor-initiating stem cells, or cancer stem cells (CSCs), undergo (epi)genetic alterations or encounter microenvironmental changes within the tumor microenvironment.

Background: Chronic constipation, diarrhea, and fecal incontinence (FI) are prevalent with significant impact on quality of life and healthcare utilization. Thyroid dysfunction was recognized as a potential contributor to bowel disturbances in selected populations, but the strength/consistency of this association remain unclear.
Aims: To investigate the relationship between thyroid function and bowel health measures (constipation, diarrhea, and FI) in a nationally representative sample of the U.

Context: Ionization and adsorption in gas discharge are similar to electrophilic and nucleophilic reactions. The molecular descriptors characterizing reactions such as electrostatic potential descriptors are useful in predicting the electrical strength of environmentally friendly gases. In this study, descriptors of 73 molecules are employed for correlation analysis with electrical strength.
