Feng, Y., Xiao, L., Li, C., Chen, S. T., & Ohuma, E. O. (2020, March 23). Statistical Methods in Medical Research.

By: Y. Feng  n, L. Xiao n , C. Li n, S. Chen n & E. Ohuma *

author keywords: Fetal health; longitudinal study; correlation; reference chart
MeSH headings : Female; Femur / diagnostic imaging; Fetal Development; Gestational Age; Humans; Longitudinal Studies; Pregnancy; Ultrasonography, Prenatal
topics (OpenAlex): Birth, Development, and Health; Pregnancy and preeclampsia studies; Statistical Methods in Epidemiology
TL;DR: Using data from the Fetal Growth Longitudinal Study of the INTERGROWTH-21st project, the longitudinal dependence of fetal head circumference, biparietal diameter, occipito-frontal diameter, abdominal circumference, and femur length is modelled using a two-stage approach.

Spine and dine: A key defensive trait promotes ecological success in spiny ants

Blanchard, B. D., Nakamura, A., Cao, M., Chen, S. T., & Moreau, C. S. (2020, April 29). Ecology and Evolution.

By: B. Blanchard *, A. Nakamura *, M. Cao *, S. Chen n & C. Moreau *

author keywords: competition; defense; morphological trait; predator-prey interactions; spines
topics (OpenAlex): Insect and Arachnid Ecology and Behavior; Plant and animal studies; Animal Behavior and Reproduction
TL;DR: Spines appear to confer broad antipredator benefits and serve as a form of defense with undetectable costs to key ecological abilities like resource foraging and competitive ability, providing an explanation for both the ecological success of the study genus and the large number of evolutionary origins of this trait across all ants.

Performance of the Population Bioequivalence (PBE) Statistical Test with Impactor Sized Mass Data

Chen, S., Morgan, B., Beresford, H., Getz, E. B., Christopher, D., Långström, G., … Lyapustina, S. (2019, August 23). AAPS PharmSciTech.

By: S. Chen n, B. Morgan*, H. Beresford*, E. Getz *, D. Christopher*, G. Långström*, H. Strickland*, C. Wiggenhorn*, S. Lyapustina

author keywords: average bioequivalence; inhalation products; in vitro performance; regulatory; US Food and Drug Administration (FDA)
MeSH headings : Administration, Inhalation; Databases, Factual / statistics & numerical data; Humans; Metered Dose Inhalers / statistics & numerical data; Nebulizers and Vaporizers / statistics & numerical data; Pharmaceutical Preparations / administration & dosage; Therapeutic Equivalency; United States; United States Food and Drug Administration / statistics & numerical data
topics (OpenAlex): Statistical Methods in Clinical Trials; Pharmaceutical Economics and Policy; Biosimilars and Bioanalytical Methods
TL;DR: This work showed that separately modeling within- and between-batch variability while increasing the number of sampled batches addressed previously identified issues of the PBE approach when between- batch variability was present, namely, increased risk for falsely concluding equivalence and low probability of correctly concluding equivalences.

author keywords: Captivity; Geometric framework; Nutrition
topics (OpenAlex): Primate Behavior and Ecology; Animal Behavior and Welfare Studies; Rabbits: Nutrition, Reproduction, Health
TL;DR: The results highlight the importance of developing nutritionally adequate diets for captive animals based on an understanding of their nutritional requirements and the need to evaluate diet variation across sites, seasons, and age–sex classes. (via Semantic Scholar)
