Annual proportions of MDR and ESBL-producing Escherichia coli (panel A) and Klebsiella spp (panel B). Results expressed as proportions in the family. Footnote (panel A. Linear regression in dotted line for ESBL-producing strains R2 = 0.283; Cochran–Armitage test p < 0.001 for ESBL-producing strains, respectively) (panel B. Linear regression in dotted line for ESBL-producing strains R2 = 0.306; Cochran–Armitage test p = 0.031 and p < 0.001 for MDR and ESBL-producing strains, respectively)
