Research Techniques Made Simple: Cost-Effectiveness Analysis

Imprint cytology: a simple, cost effectiveness analysis for diagnosing Helicobacter pylori, in west of Iran

 Background: This study was to determine the sensitivity, specificity, positive predictive value (PPV), negative predictive values (NPV) and agreement between two methods of the stained gastric imprint cytology smears and stained gastric specimen biopsy mucosal methods for detection of H. pylori. Methods: Air-dried imprint smears of gastric biopsies from 330 patients were stained by the Grunwal...

Cost-Effectiveness analysis of malaria diagnosis techniques in patients with suspected malaria in Hormozgan province- 2012

Introduction: Since ancient times Malaria in Iran has been considered as a serious health risk, especially in Hormozgan Province, as no other disease like Malaria has imposed irreparable financial and life losses to the country. Since saving costs in the healthcare sector comes as first priority in most countries, this study aims at launching a cost-effectiveness analysis on malaria diagnosis d...

Research Techniques Made Simple: Workflow for Searching Databases to Reduce Evidence Selection Bias in Systematic Reviews.

Clinical trials and basic science studies without statistically significant results are less likely to be published than studies with statistically significant results. Systematic reviews and meta-analyses that omit unpublished data are at high risk of distorted conclusions. Here, we describe methods to search beyond bibliographical databases to reduce evidence selection bias in systematic revi...

Comparative efficiency research (COMER): meta-analysis of cost-effectiveness studies

BACKGROUND The aim of this study was to create a new meta-analysis method for cost-effectiveness studies using comparative efficiency research (COMER). METHODS We built a new score named total incremental net benefit (TINB), with inverse variance weighting of incremental net benefits (INB). This permits determination of whether an alternative is cost-effective, given a specific threshold (TIN...
