  1. Group AUTI- and BUTI- were classified as patients in group A and group B without overt UTI. *mean ± standard deviation (SD).
  2. † P value calculated using the One-Way ANOVA. Post-hoc analyses were performed using the Scheffe’s method.
  3. ‡ Estimated glomerular filtration rate (eGFR) was calculated using the CKD-EPI equation (ml/min/1.73m2).
  4. ΔeGFR, annual reduction rate of estimated glomerular filtration rate; eGFR, estimated glomerular filtration rate; ESRD, end stage renal disease; F/U, follow-up; HTN, hypertension; UTI, urinary tract infection.
