Objectives: The value of a health technology can be measured in terms of cost and benefit on two-dimensional co-ordinates. This study is to quantitatively analyze the correlation and to conduct a regression on the X-Y plane constituted by cost and QALYs (quality-adjusted life years) associated with the first line treatment, the maintenance treatment, and the second line treatment for non-small cell lung cancer (NSCLC).

Methods: The cost-effectiveness data of the cost and QALYs were extracted, with respect to the three categories of the NSCLC treatment, from the CEA Registry at Tufts Medical Center, regarding the literature published from 2000-2011.

Background: The purpose of this study was to assess the 1-year clinical, functional, and safety-related outcomes following a switch to olanzapine of at least one typical antipsychotic drug in the previous regimen in the treatment of patients of schizophrenia in Japan.

Methods: Using data from a large 1-year prospective, multicenter, naturalistic study of olanzapine for the treatment of schizophrenia in Japan, patients who were switched from any oral typical antipsychotic to olanzapine were identified. Mixed models for repeated measures, controlling for baseline demographics, were utilized to assess outcomes for clinical and functional measures.
