value 1 represents the value for the comparison between the group of hypomagnesemia and the group of normomagnesemia. value 2 represents the value for the comparison between the group of hypermagnesemia and the group of normomagnesemia. APTT: activated partial thromboplastin time; LOS: length of stay.
