Extended Data Fig. 2: Gene expression variance analysis.
From: Dysregulation of brain and choroid plexus cell types in severe COVID-19
a, PVCA, displaying the gene expression variance explained by residuals (biological and technical noise) or experimental factors such as brain region, age, sex and respective combinations. n = 30 samples. b, Principal component (PC) analysis visualization of all samples, based on unscaled counts. c, UMAP projections of nuclei isolated from the medial frontal cortex (top) or choroid plexus (bottom), and split by disease group, showing no systematic batch effects.
