*
(F): female, reference is male; (M): male, reference is female (reference is the counterpart of the gender indicated in parentheses). Morganella morganni: OR = 10.15 (95% CI: 6.53-15.76), p < 0.0001 (male); Pseudomonas aeruginosa: OR = 4.81 (95% CI: 3.40-6.82), p < 0.0001 (male); Staphylococcus saprophyticus: OR = 10.37 (95% CI: 3.84-28.0), p < 0.0001 (female); Enterobacter aerogenes: OR = 1.48 (95% CI: 1.08-2.02), p = 0.012 (male).
