Spearman correlations between the age of the sample donor (20–70 years) and estimated proportions of neuronal, glial, and endothelial cells.

Statistically significant p-values (p-value < 0.05) are marked with *. Also shown are the median and mean proportions, showing proportionate prevalence (between 0 and 1) of each cell type out of all cells. These statistics are shown both for all sample donors and separately for male and female sample donors.
