The ‘adjusted p values’ throughout this paper were corrected for multiple testing by the Benjamini–Hochberg correction (Benjamini & Hochberg, 1995), which controls for false discovery rate. The well‐known Bonferroni method controls for the family‐wise error rate. The adjusted p values are reported in the padj. column.
