Exact Properties of Some Heteroscedastic TOST Alternatives for Bioequivalence

Gwowen Shieh, Show-Li Jan & Cheng-Shiun Leu
The two one-sided tests (TOST) procedure is the common method for assessing bioequivalence between two different drugs or formulations of the same drug. Several solutions to Behrens-Fisher problem have been extended to establish statistical equivalence under variance heterogeneity. Unlike other existing studies that rely exclusively on simulation results, the analytical formulas of power and Type I error rate are derived. Exact numerical investigations were conducted to evaluate the behavior of the Welch–Satterthwaite, Cochran–Cox, and Banerjee–McCullough...

Prediction of intrahepatic cholestasis of pregnancy in the first 20 weeks of pregnancy

Xinyuan Zhang, Yu Chen, Stephen Salerno, Yi Li, Libin Zhou, Xiaoxi Zeng & Huafeng Li
Intrahepatic cholestasis of pregnancy (ICP) is a pregnancy-specific liver disease associated with a significant risk of fetal complications including pre-term delivery and fetal death. Typically, it was diagnosed in the third trimester of pregnancy. This study utilized characteristics from routine maternal examinations in the first 20 weeks’ gestation to predict ICP in pregnant women. This is a retrospective case-control study. 13,329 medical records were collected on pregnant women presenting to the West China Second University...

Steller’s sea cow, an extinct sirenian and one of the largest Quaternary mammals, was described by Georg Steller in 1741 and eradicated by humans within 27 years. Here, we complement Steller’s descriptions with paleogenomic data from 12 individuals. We identified convergent evolution between Steller’s sea cow and cetaceans but not extant sirenians, suggesting a role of several genes in adaptation to cold environments. Among these are inactivations of lipoxygenase genes, which in humans and mouse...
