a
The breakdown of isolates which did not cause an infection and therefore excluded from the model as they predicted colonization perfectly.
b
Other species were Kluyvera intermedia (N=1), Morganella morganii (N=1), Proteus mirabilis (N=1) and unknown species of Enterobacterales (N=2) which could not be speciated further in a clinical laboratory.
