Similarly, the sensitivity analysis of the factors affecting resistance rates also confirmed that there was no significant temporal changes for all Acinetobacter isolates and when considering ACB isolates only (the temporal trend was marginally significant for ACB with P = 0.042; Additional file 1 : Table S1), and that the North East region had higher rates on average than other regions (resistance rates in the sensitivity analyses ranging from 1.0 to 11.1 and 0 to 24.0% for ACB isolates).
