Incidence rates per 100 person-years of first episodes of bloodstream infection among hemodialysis patients by potential risk factors.

Abbreviations: No., Number of first episodes of bloodstream infection; IRR incidence rate ratio; CI, confidence interval; AV fistula, arteriovenous fistula.a Per 1 00 person-years.b Adjusted for all variables in the table and time since study entry using Poisson Regression.c Calculated for the corresponding adjusted incidence rate ratios using Poisson regression.d Three levels of comorbidity was created based on the modified Charlson comorbidity index (m-CCI) score at the date of first treatment with renal replacement therapy “Low” (CCI = 0), “Medium” CCI 1–2, and “High” CCI > 2. Renal diagnosis was not included in the m-CCI score. See text for details.f A time varying covariate categorizing risk time in two categories based on the date of first arteriovenous fistula surgery.Incidence rates per 100 person-years of first episodes of bloodstream infection among hemodialysis patients by potential risk factors.
