Development of a Model to Estimate 24-Hour Urinary Creatinine Excretion

摘要: The accuracy of the spot urine analyte/creatinine ratio in estimating 24-hour excretion analyte is compromised because it not adjusted for creatinine excretion. authors developed a model conveniently was derived from collections using multiple linear regression, including sex, weight, race, and age. then evaluated validation cohort, assessing correlation between estimated measured by comparing their with muscle mass. Estimated correlated strongly (r=0.80 entire cohort 0.93 after eliminating patients incomplete collections), at least as lean mass (r=0.94 vs r=0.82, respectively). Adjusting ratios this convenient method can improve albumin, sodium, other analytes.
