Consequences of Traffic Accidents Transferred by Helicopter and Ground Ambulance: Propensity Score Matching
Introduction: The main task of the emergency medical system is to provide primary care and transfer the injured to a medical center. Studies have been conducted to investigate the outcome of helicopter and ground ambulance casualties, but they show different results. These different results may be due to the type of study, statistical methods, differences in pre-hospital emergency systems, an...
متن کاملA Propensity Score Matching Analysis
The purpose of this paper is to determine how much is the “bonus” or “prize” to the sales per worker of Internet-using firms compared to not Internet-using firms. The author employs matching techniques based on an Argentinean database. The author first presents a binary logit model, in which the dependent variable is a dichotomous variable equal to 1 if the firm adopted Internet and 0 otherwise...
متن کاملPropensity score matching and complex surveys
Researchers are increasingly using complex population-based sample surveys to estimate the effects of treatments, exposures and interventions. In such analyses, statistical methods are essential to minimize the effect of confounding due to measured covariates, as treated subjects frequently differ from control subjects. Methods based on the propensity score are increasingly popular. Minimal res...

متن کاملA population-based propensity score matching analysis
Background: Previous studies suggested an impaired endothelial function in patients with diabetes. However, the validity of this finding may be limited by the lack of adequate adjustment for further cardiovascular confounders. We assessed endothelial function as measured by flow-mediated dilation (FMD) of the brachial artery in patients with either type 1 or type 2 diabetes in comparison with n...
