  1. Values are frequencies and percentages. Combined biomarkers and C-PCR: two consecutive determinations positives or/and at least one of each biomarkers (in one determination) positive. C-PCR: one determination positive
  2. NCI neither colonized nor infected, LGCC low-grade Candida spp. colonization, HGCC high-grade Candida spp. colonization, IAC intra-abdominal candidiasis, BDG (1-3)-ß-D-glucan, CAGTA Candida albicans germ tube antibody, mannan-Ag mannan antigen, mannan-Ab mannan antibody, C-PCR PCR-based Candida detection
  3. Different superscripts (a,b,c) indicate nominally significant differences (P < .05)
