Effects of IGFBP4 deficiency on human preadipocyte proliferation and differentiation through the IGF1R/AKT pathway

FEBS Open Bio, EarlyView.
IGFBP4 knockdown (KD) impairs preadipocyte proliferation and is associated with IGF1R protein downregulation and attenuated AKT phosphorylation. The mechanisms by which IGFBP4 KD influences the IGF1R/AKT signaling pathway involve newly synthesized proteins and lysosomal degradation pathways. Created in BioRender.

Differential Item Function

2016
For every IRT model, a mathematical function is used to specify the probability of item responses as a function of the ability (latent trait). The degree to which the observed data fit the mathematical function needs to be examined since valid results can only be drawn if the data fit the model.

Estimating the Importance of Differential Item Functioning

Journal of Educational and Behavioral Statistics, 1995
Several methods have been proposed to detect differential item functioning (DIF), an item response pattern in which members of different demographic groups have different conditional probabilities of answering a test item correctly, given the same level of ability. In this article, the mixture index of fit, proposed by Rudas, Clogg, and Lindsay (1994) ,
