a trend toward significancep = 0.076
A Welch’s two-sample t test of PC1 scores revealed that AHR activation showed a trend toward significance ( t = 2.68, p = 0.076), whereas no meaningful effects were observed for other pathways: AR (t = 0.48, p = 0.68), ER ( t = − 0.93, p = 0.43), and SP1 ( t = 0.37, p = 0.74) (Supplementary Fig. 4c ).
