The amount of water, creatinine, electrolytes, proteins, and enzymes were higher during the day (up to three fold, p always less than 0.05), while equal amounts of amino acids were ex...
متن کاملCorrelation versus agreement; protein/creatinine ratio in spot urine and 24-hour urine protein.

متن کاملCan overnight urine replace 24-hour urine collection to asses salt intake?
Are overnight urine specimens adequate for characterizing the daily salt intake of individuals, i.e., can the overnight specimen replace the 24-hour specimen? Data from 142 male participants of an ongoing trial on the primary prevention of hypertension were used to examine this question with correlation analysis and quantile classification. Estimated correlation between the true mean 24-hour an...
