NOG, Nonobese group; CWG, corrected ideal body weight group; RWG, real body weight group; T0, T15, T30, T60, T120, and T240: baseline and 15, 30, 60, 120, and 240 min after magnesium sulfate administration. Two-wayrepeated-measures analysis of variance. The control group was not represented here because there were no changes in this group over time.
