To adjust or not to adjust? It is not a matter of if, but how

Published on 2026-05-22 by @MIT

Abstract: AbstractTotal intracranial volume (TIV) is a major confounding factor in neuroimaging studies, particularly when studying sex differences in the brain. Different methods have been proposed to adjust for this effect; however, their impact has not been directly studied and compared. Furthermore, when studying cortical metrics at the vertex level, the choice of smoothing level can impact analysis outcomes which can in turn impact the degree of TIV-based biases and the effectiveness of the correctio[...]


Our summary: This study evaluates the impact of four adjustment methods for total intracranial volume (TIV) on neuroanatomical sex differences. It finds that adding TIV as a covariate is the most effective method for reducing bias. Additionally, the choice of smoothing level can influence the estimation of sex differences in cortical metrics.

Abstract: npj Biodiversity, Published online: 15 May 2026; doi:10.1038/s44185-026-00131-yScientific collaborations in the Amazon often reproduce historical and structural inequalities that limit local leadership in knowledge production. Although funding and international attention have increased, local researchers are often confined to data collection while external actors define research priorities and receive intellectual recognition. Based on my trajectory as an Amazonian scientist, I argue that decolo[...]


Our summary: Decolonial science in the Amazon seeks to address historical inequalities in research. Local researchers are often sidelined in decision-making and recognition. Structural transformation and sustained investment in local leadership are essential for equitable scientific collaboration.
