For each of the first two axes of the FCA (z1 and z2), % of total inertia, and nonparametric (Spearman's) correlation coefficients between z-values and CAI-Eco (codon adaptive index of the E. coli ortholog), GC content, AT skew (ATs) and GC skew (GCs) indices indicating codon positions. Bold values are significant at the 0.05 level (*) or at the 0.01 level (**) after Bonferroni's correction for multiple tests (k = 5); Sokal and Rohlf (2003).
