Cecilia de Oliveira, Ana Paula de Oliveira, Marcelo de Oliveira, and Roberto de Oliveira Salles, have been removed from the study, and a third author has been assigned the responsibility for the safety oversight and the study design. Dr. Salles is collaborating with Dr. Oliveira in the current study.
No new analyses or analyses with patients were found during the search process. However, as a result of the significant number of eligible samples from the study, additional data will be requested from the other sites participating in the study for additional analyses.

Introduction
Dietary potassium intake is the major determinant of plasma potassium content. The prevalence of potassium deficiency has dramatically decreased in the last few decades [1]. Additionally, the prevalence of hyperkalemia (pregnancy-associated hyperkalemia defined as a potassium content of 500 mEq/L) has been reported in pregnancy [2].
Although serum potassium and potassium excretion have been found to depend on sex and age, dietary sources may have a greater influence on blood pressure and the development of cardiovascular disease than previously thought.
In general, the serum concentration of potassium is not a good predictor of cardiovascular diseases in people with normal blood pressure, despite the fact that high blood pressure is a risk factor for cardiovascular diseases [3]. High blood pressure is a strong independent risk factor for developing type 2 diabetes mellitus (T2DM) and cardiovascular disease (CVD
