Individual Participant Data Meta-Analysis for a Binary Outcome: One-Stage or Two-Stage?
BACKGROUND A fundamental aspect of epidemiological studies concerns the estimation of factor-outcome associations to identify risk factors, prognostic factors and potential causal factors. Because reliable estimates for these associations are important, there is a growing interest in methods for combining the results from multiple studies in individual participant data meta-analyses (IPD-MA). W...
متن کاملMeta-analysis of Gaussian individual patient data: Two-stage or not two-stage?
Quantitative evidence synthesis through meta-analysis is central to evidence-based medicine. For well-documented reasons, the meta-analysis of individual patient data is held in higher regard than aggregate data. With access to individual patient data, the analysis is not restricted to a "two-stage" approach (combining estimates and standard errors) but can estimate parameters of interest by fi...
متن کاملEstimating Capacity Utilization in Two-Stage Production Systems: A Data Envelopment Analysis Approach
The current study investigates performance in two-stage production systems through the measurement of capacity utilization (CU). In short-run, the degree of capacity utilization depends on the ability of decision making units to utilize fixed production factors. To develop this indicator in two-stage production processes, a modified SBM network DEA model is proposed. A numerical example is also...
متن کاملMeasuring the efficiency of a three-stage network using data envelopment analysis approach considering dual boundary
This paper presents a method for performance evaluation, ranking and clustering based on the double-frontier view to analyze the complex networks. The model allows us to open the structure of the “black box” and can help to obtain important information about efficient and inefficient points of the system. In this paper, we consider a three-stage network, in respect to the additional desirable a...
متن کاملComparison of one-stage free gracilis muscle flap with two-stage method in chronic facial palsy
Abstract Background: Rehabilitation of facial paralysis is one of the greatest challenges faced by reconstructive surgeons today. The traditional method for treatment of patients with facial palsy is the two-stage free gracilis flap which has a long latency period of between the two stages of surgery. Methods: In this paper, we prospectively compared the results of the one-stage gracilis flap ...
