Is network meta-analysis as valid as standard pairwise meta-analysis? It all depends on the distribution of effect modifiers
Jansen, Jeroen P.; Naci, Huseyin - London School of Economics (LSE) - 2013
Background In the last decade, network meta-analysis of randomized controlled trials has been introduced as an extension of pairwise meta-analysis. The advantage of network meta-analysis over standard pairwise meta-analysis is that it facilitates indirect comparisons of multiple interventions...

Methodological Considerations in Cost-Effectiveness Analysis
Alemayehu, Demissie - International Institute of Social and Economic Sciences - 2014
In decision making regarding optimal resource allocation to safeguard public health, policymakers and healthcare providers rely on the availability and reliability of data about the relative costs and benefits of competing treatment options. One such an approach is based on cost effectiveness...

Semi-Parametric Estimation and Inference for the Mean Outcome of the Single Time-Point Intervention in a Causally Connected Population
Sofrygin, Oleg; van der Laan, Mark J. - In: Journal of Causal Inference 5 (2016) 1
recent methodological advances in the field of targeted maximum likelihood estimation (TMLE) and describe an estimation …-generating distribution. With this key insight in mind, we describe the TMLE for possibly-dependent units as an iid data algorithm and we …

We offer a non-parametric plug-in estimator, the targeted maximum likelihood estimator (TMLE) and the cross …-validated TMLE (CV-TMLE), to simultaneously estimate both the average and variance of the stratum-specific treatment effect function …. The CV-TMLE is preferable because it guarantees asymptotic efficiency under two conditions without needing entropy …

The causal effect of family physician program on the prevalence, screening, awareness, treatment, and control of hypertension and diabetes mellitus in an Eastern Mediterranean Regi...
Mohammadi, Neda; Alizadeh, Ahad; Moghaddam, Sahar Saeedi; … - In: BMC Public Health 23 (2023) 1, pp. --
Hypertension (HTN) and diabetes mellitus (DM) as part of non-communicable diseases are among the most common causes of death worldwide, especially in the WHO’s Eastern Mediterranean Region (EMR). The family physician program (FPP) proposed by WHO is a health strategy to provide primary health...

Bayesian Exploratory Factor Analysis
Conti, Gabriella; Frühwirth-Schnatter, Sylvia; … - 2014
This paper develops and applies a Bayesian approach to Exploratory Factor Analysis that improves on ad hoc classical approaches. Our framework relies on dedicated factor models and simultaneously determines the number of factors, the allocation of each measurement to a unique factor, and the...

The effect of identifiability on the relationship between risk attitudes and other-regarding concerns
Koukoumelis, Anastasios; Levati, M. Vittoria; Ploner, Matteo - 2013
Previous studies have shown that other-regarding concerns are weakened under risky situations. Daily experience also suggests that people care more about an identifiable than about an unidentifiable third person. We report on an experiment designed to explore whether rendering the other...

The Event-History Approach to Program Evaluation
Abbring, Jaap H. - 2006
This paper studies the event-history approach to microeconometric programevaluation. We present a mixed semi-Markov event-history model, discussits application to program evaluation, and analyze its empirical content.The results of this paper provide fundamental insights in what can be...
