What is the appropriate statistical procedure to test whether mean urinary protein has changed over the 8-week period? 

Renal Disease

Ten patients with advanced diabetic nephropathy (kidney complications of diabetes) were treated with captopril over an 8-week period [9]. Urinary protein was measured before and after drug therapy, with results listed in Table 8.16 in both the raw and ln scale.
