Table 2 Microbiologic and valve characteristics of cases undergoing surgery for infective endocarditis

From: Long term surgical outcomes for infective endocarditis in people who inject drugs: a systematic review and meta-analysis

Microbiology

Valve data
  Number of valves Mitral Aortic Tricuspid Pulmonary Multiple Embolic events Prosthetic valve
PWID 922 236 (25.6) 366 (39.7) 309 (33.5) 11 (1.2) 145 (15.7) 190 (24.1) 62 (7.9)

  1. Abbreviations: CONS Coagulase-negative staphylococci, GNR Gram negative rods; non-PWID People who do not inject drugs, PWID People who inject drugs
  2. Numbers denote n (%)
  3. Percentages were calculated based on the number of pathogens for the microbiologic variables or number of valves reported for the valve-related variables
