Change in Maximal Rate of Urea Synthesis (MRUS) Level (mg Urea N/hr/kg Body Weight) by
Question: Problem 5
| Change in Maximal Rate of Urea Synthesis (MRUS) Level (mg Urea N/hr/kg Body Weight) by Group | ||||||||
| Group Change in MRUS Values | ||||||||
| Selective Shunt | -3 | 20 | -6 | -5 | -3 | -3 | -6 | 12 |
| Nonselective Shunt I | -18 | -4 | -18 | -18 | -6 | -18 | ||
| Nonselective Shunt II | -24 | -7 | -15 | 4 | -14 | -8 | -11 | |
The data shown here, taken from Brogan and Kutner (1980), are the change in the maximal rate of urea synthesis (MRUS) level for cirrhotic patients who underwent either a standard operation (a nonselective shunt) or a new procedure (a selective shunt). The purpose of the operations was to improve liver function, measured by MRUS. A low value of MRUS is associated with poot liver function. Patients in the nonselective shunt group are divided into two groups based on the preoperative MRUS values (< 40 and > 40).
Perform an analysis of variance of these data at the 0.05 significance level to determine if there is a difference in the three groups. If there is a significant difference, use an appropriate multiple comparison procedure to find the source of the difference.
