Example Sentences:
(1) Renal function was estimated by the formula of Cockcroft and Gault.
(2) The other two methods were predictive methods: the Kampmann nomogram and the formula developed by Gault and Cockcroft.
(3) Among the numerous mathematical equations, CLCR as estimated by the method proposed either by Mawer or Cockcroft and Gault was the best predictor of CLIN (CLIN = 1.05CLRCR - 18.38 or CLIN = 1.12CLCR - 20.60, respectively; r = 0.81; p less than 0.0001).
(4) CrCLs using the equations of Cockroft-Gault (CGCL), Jelliffe (JCL), and Jelliffe uncorrected for body surface area (JCLu) were calculated, then compared to the AGCL.
(5) To judge whether formulas estimating creatinine clearance from serum creatinine levels are reliable, we also compared 24-hour creatinine clearances measured in 50 inpatients with values calculated by the Cockroft-Gault equation.
(6) Creatinine clearance in each patient was determined by the Cockroft and Gault method (1).
(7) The accuracy and precision of estimates of glomerular filtration rate (GFR) from serum creatinine, age, sex and body weight using the methods proposed by Cockroft and Gault and by Siersbaeck-Nielsen et al, were determined in 234 subjects on 574 occasions.
(8) When the creatinine clearance as calculated by the method of Cockcroft and Gault from the patient's age, weight, and serum creatinine was compared to the measured creatinine clearance in the same patients, the correlation coefficient was low (r = 0.40) and the average difference between the predicted and measured creatinine clearance values was 25.3%.
(9) The predictive accuracy of the Cockroft and Gault equation in the assessment of creatinine clearance was evaluated in 30 Nigerian patients with hypertension, congestive heart failure, chronic renal failure and varying degrees of renal impairment.
(10) The predictive value of the Cockcroft-Gault equation in patients with Cushing's syndrome was evaluated in 23 patients.
(11) The Jelliffe 1973 equation with modified lean body weight was the best equation, followed by the Cockcroft-Gault equation.
(12) Aminoglycoside serum concentrations were used to estimate GFR and were compared with the two measured methods and a creatinine clearance calculated with the Cockcroft-Gault method (ClCG).
(13) Estimated creatinine clearance (EClcr) values were obtained by the Cockcroft-Gault method using ideal body weight (IBW) and total body weight (TBW).
(14) In healthy subjects CLcr calculated by the formulae of Cockcroft & Gault (1976) and Mawer et al.
(15) Predicted Ccr values were derived from Scr using the methods of Cockcroft and Gault (Method II), Siersbaek-Nielsen, Kampmann and others (Method III) and Jeliffe (Methods I and IV).
(16) When all of the subjects with a wide range of CLcr (3.1-164) were considered all formulae gave good correlations, but the formula of Cockcroft & Gault (1976) gave the best estimate.
(17) Thus, in our patient population, creatinine clearance calculated by the method of Cockcroft and Gault did not correlate well with measured creatinine clearance and thus was not useful as a clinical tool.
(18) In patients with cancer treated with cisplatin, carboplatin or methotrexate creatinine clearance calculated using the Cockcroft-Gault formula was compared with measured clearance and with the glomerular filtration rate.
(19) Their accuracy declined in the order from the calculated creatinine clearance according to Cockcroft and Gault via the inverse value of the serum creatinine concentration towards the 24-hour creatinine clearance.
(20) (Huang S-N, Millman I, O'Connell A, Aronoff A, Gault H, Blumberg BS: Am J Pathol 67: 453, 1972) nuclear eosinophilic inclusions due to excess HBcAg particles have been identified in cases of chronic hepatitis B virus infection.
