Data are presented as frequency (with percentage). * patients presenting with hypomagnesemia (24-h magnesium excretion ≥ 500 µmol or a fractional magnesium clearance ≥ 2.0 × 10−2); ** patients presenting with hypokalemia and metabolic alkalosis (24-h chloride excretion ≥ 20 mmol or fractional chloride clearance ≥ 0.5 × 10−2).
