WebOct 11, 2024 · Background: 24-h urine collection is regarded as the “gold standard” for monitoring sodium intake at the population level, but ensuring high quality urine samples is difficult to achieve. The Kawasaki, International Study of Sodium, Potassium, and Blood Pressure (INTERSALT) and Tanaka methods have been used to estimate 24-h urinary … WebThe Pearson correlation coefficient test compares the mean value of the product of the standard scores of matched pairs of observations. Once performed, it yields a number that can range from -1 to +1. Positive figures are indicative of a positive correlation between the two variables, while negative values indicate a negative relationship.
