Table 1. Definition for CKD prevalence.

Definition Criteria
1 Albuminuria ≥30mg/g
  And/or
eGFRa <60 ml/min/1.73 m2
2 eGFRa <60 ml/min/1.73 m2
1 and 2 No chronicity criterionb

Abbreviation: eGFR, estimated glomerular filtration rate.

a

eGFR calculated using the CKD-EPI formula.

b

Chronicity criterion (persistence of albuminuria or decreased eGFR for ≥3 months) could not be used as only four studies had this available.
