Evaluating Model Specification When Using the Parametric G-Formula in the Presence of Censoring.
Chiu YH, Wen L, McGrath S, Logan R, Dahabreh IJ, Hernán MA. Chiu YH, et al. Am J Epidemiol. 2023 Nov 3;192(11):1887-1895. doi: 10.1093/aje/kwad143. Am J Epidemiol. 2023. PMID: 37338985 Free PMC article.
An informal approach for evaluating model specification is to compare the observed distributions of the outcome, treatments, and confounders with their parametric g-formula estimates under the "natural course." In the presence of loss to follow-up, however, the obse …

Neutrophils Release Metalloproteinases during Adhesion in the Presence of Insulin, but Cathepsin G in the Presence of Glucagon.
Fedorova NV, Ksenofontov AL, Serebryakova MV, Stadnichuk VI, Gaponova TV, Baratova LA, Sud'ina GF, Galkina SI. Fedorova NV, et al. Mediators Inflamm. 2018 Feb 14;2018:1574928. doi: 10.1155/2018/1574928. eCollection 2018. Mediators Inflamm. 2018. PMID: 29670459 Free PMC article.
The total amount of secreted proteins defined as the sum of detected amino acids was increased in the presence of insulin and reduced in the presence of glucagon. E2 did not affect the amount of protein secretion. ...In contrast, glucagon induced the secretion of ca …
