Key result
The median prevalence of chronic kidney disease was 7.2% in persons aged 30 years or older, with estimates strongly depending on whether the MDRD or Cockcroft-Gault equation was used.
Systematic Review
CKD is highly prevalent in the general population, particularly among the elderly, but prevalence estimates vary significantly depending on whether the MDRD or Cockcroft-Gault equation is used.
No takes yet. Share an insight, caveat, or question.
Substantial CKD burden in adults ≥30 warrants clinical awareness; confirms GFR equation choice drives major prevalence variability, needing standardization.
Zhang et al. (2008) conducted a systematic review in Chronic kidney disease. MDRD equation vs. Cockcroft-Gault (CG) equation was evaluated on Prevalence of chronic kidney disease. The median prevalence of chronic kidney disease was 7.2% in persons aged 30 years or older, with estimates strongly depending on whether the MDRD or Cockcroft-Gault equation was used.
