| Item | Formula / Note | Source / Standard |
|---|---|---|
| Estimation equation | estimated filtration rate comes from creatinine age and sex in an empirical equation | MDRD 175 simplified equation (Levey 2006) |
| Staging criteria | chronic kidney disease stages by filtration rate with below sixty for three months | KDIGO 2012, CKD evaluation |
| Interpretation caveat | abnormal muscle mass biases estimates and cystatin C based equations help | KDIGO 2012, CKD evaluation |
