An equation for predicting endogenous creatinine clearance (CrCl) in adults and children (with both stable and unstable renal function) from serum creatinine concentration is presented. The predictions are compared with four other available estimating methods, bases on values in 110 subjects with renal impairment of widely differing degrees. In patients with stable and with unstable renal function the corelaion between measured and predicted CrCl was better with the new equation. In patients with rapid changing renal function the new equation resulted in accurate predictions CrCl within a few hours after the change, as opposed to several with the other methods. The elimination rate constant of the aminoglycoside antibiotic amikacin correlated more precisely with CrCl values estimated from the new equation that with those measured doing 24 hr or with the other prediction methods.

D011336 Probability The study of chance processes or the relative frequency characterizing a chance process. Probabilities
D012044 Regression Analysis Procedures for finding the mathematical function which best describes the relationship between a dependent variable and one or more independent variables. In linear regression (see LINEAR MODELS) the relationship is constrained to be a straight line and LEAST-SQUARES ANALYSIS is used to determine the best fit. In logistic regression (see LOGISTIC MODELS) the dependent variable is qualitative rather than continuously variable and LIKELIHOOD FUNCTIONS are used to find the best relationship. In multiple regression, the dependent variable is considered to depend on more than a single independent variable.
