Figure 1b displays the corrplot map for 100 DEGs in the training dataset. The “corrplot” R package was used to generate a visual representation of the correlation matrix. Various parameters, such as color, font size, and line width, were adjusted to clarify the displayed correlation information. The results showed a high correlation between Rela and Stat3 in SA-AKI cells (Figure 1b). This evidence concerns the gene STAT3 and acute kidney injury.
