Table 1.

Indirect estimation of NEAP, according to available equations [27]

Author Equation
Frassetto et al. NEAP (mEq/day) = [0.91 × protein (g/day) − 0.57 × potassium (mEq/day)] + 21
NEAP (mEq/day) = [54.5 × protein (g/day)/potassium (mEq/day)] − 10.2
Remer et al. NEAPest (mEq/day) = PRAL * + OAest
Sebastian et al. NEAPest (mEq/day) = PRAL + OAest §

* PRAL (mEq/day) = 0.49 × protein (g/day) + 0.037 × phosphorus (mg/day) − 0.021 × potassium (mg/day) − 0.026 × magnesium (mg/day) − 0.013 × calcium (mg/day) [27]. OAest (mEq/day) = body surface area × 41/1.73 [27]. § OAest (mEq/day) = 32.9 + 0.15 × [sodium (mg/day) + potassium (mg/day) + calcium (mg/day) + magnesium (mg/day) − chloride (mg/day) – phosphorus (mg/day)].
