Late (seven days or more following birth) higher may leads to lower hyponatraemia (< 130 mmol/L) compared with lower sodium intake (low certainty).
It is very uncertain whether late (seven days or more following birth) higher changes hypernatraemia (≥ 150 mmol/L) compared with lower sodium intake (very low certainty).
