Prior to correction for multiple testing, 16 of 156 correlations were significant at the P < 0.05 level, but only a single correlation remained nominally significant after Holm–Bonferroni correction (SOD‐TAC, r = −0.28, P = 0.02.
However, regardless of the direction of correlations, if a particular set of OS markers were indeed reflecting a unified redox system of molecular damage and AOX defense at the organismal level, meaning that single markers could be interpreted to capture general redox variation, we would expect strong, highly significant correlations among markers that remain broadly stable across environmental conditions, ages, and sexes.
