  1. PD peritoneal dialysis, AVF arteriovenous fistula, TC tunneled catheter, NTC non-tunneled catheter, MCCI Modified Charlson comorbidity index, CIN chronic interstitial nephritis, DM diabetes mellitus, GN glomerulonephritis, PKD polycystic kidney disease, NS not significant, CNS Coagulase Negative Staphylococci. For a full disclosure of microorganisms included in each of the 13 microbial groups outlined in this table, see Additional file 1. The P value is calculated as the overall difference between groups or the overall difference of distribution between groups
  2. a Defined as the ability of the organism to coagulate plasma, i.e. all other Staphylococci than S. aureus
  3. b Only the genus was reported, not the species
  4. c A positive blood cultivation was reported without genus or species
