Abstract: The effect of prophylactic administrative of magnesium on postoperative cardiac arrhythmias is controversial and there are antonym results in the literature. We studied the relationship between prophylactic magnesium and cardiac arrhythmic using two different statistical approaches. These two approaches are the ordinary logistic regression and generalized additive logistic regression. The ordinary logistic regression was unable to show any significant relation between magnesium level and post coronary artery bypass graft surgery atrial fibrillation while generalized additive model supported the significant effect of magnesium level on atrial fibrillation. These findings may provide new insights into the possible explanation of magnesium effect on atrial fibrillation when we consider the nonlinearity for the effects of studied variables. |
Keywords and phrases: magnesium, postoperative cardiac arrhythmias, atrial fibrillation, generalized linear model, generalized additive logistic regression. |
