You should write PC1 explains 82% of variance and PC2 6% line 286: "most substantial differences by tens of orders of magnitude greater were found between" remember the P values does not give you the idea of magnitude differences so remove this...you just got highly significant differences.....be aware that this using all variables...if you re-try using only the PCs that explain 95% of variance (e.g. the first five...) you will see few non-significant differences.
