An open-label, randomized, 24-week, parallel group, flexible-dose study demonstrated noninferiority of OROS hydromorphone ER vs. twice-daily oxycodone CR in patients with chronic noncancer pain. In total, 112 patients were enrolled in ... 252 Tan Hung-Jui - - 2012 Although partial nephrectomy is the preferred treatment for many patients with early-stage kidney cancer, recent clinical trial data, which demonstrate better survival for patients treated with radical nephrectomy, have generated new uncertainty regarding the comparative effectiveness of these treatment options. To compare long-term survival after partial vs radical nephrectomy among ... 253 McManus I C - - 2012 Background: In high-stakes assessments in medical education, such as final undergraduate examinations and postgraduate assessments, an attempt is frequently made to set confidence limits on the probable true score of a candidate.
