The Nordic Arthroplasty Register Association (NARA) was established in 2007 by hip and knee arthroplasty registry leaders from Denmark, Norway, and Sweden. Purportedly, the idea of combining national databases was presented and discussed while sitting in a bar. Read the editorial at https://www.tandfonline.com/doi/full/10.1080/17453674.2021.1947006

In this article, we examine study designs for extending (generalizing or transporting) causal inferences from a randomized trial to a target population. Specifically, we consider nested trial designs, where randomized individuals are nested within a sample from the target population, and nonnested trial designs, including composite data-set designs, where observations from a randomized trial are c

A key misunderstanding is the belief that the goal of a causal analysis is to “detect” an effect. Causal effects are not binary signals that are either detected or undetected; causal effects are numerical quantities that need to be estimated.

I ramverket kommer vi använda kunskap om biologisk mångfald, ekologiska processer, miljöpsykologi, och epidemiologi för att hitta en gemensam väg framåt för att bemöta dessa globala utmaningar i praktiken. Vi rekryterar nu tre postdoktorer som tillsammans kommer att koordinera forskningen i projektet. Läs mer och sök tjänsterna på https://lu.varbi.com/what:job/jobID:422401/

Spine surgery research has improved considerably over the last few decades. Its’ most recent growth is in large part due to the mounting increase in studies conducted using national databases and registries. With easy access to a large number of patients, the benefit of these registries has become evident. However, as with any research, this type of data must be used responsibly with the appropria

We identified 3 examples of suboptimal bias analysis, one for each common bias. For each, we describe the original research and its bias analysis, compare the bias analysis with good practices, and describe how the bias analysis and research findings might have been improved.

In this paper, we describe the use of the target trial framework for designing agent-based models when the goal is estimation of causal effects in the presence of interference, or spillover. Read the paper at https://academic.oup.com/aje/article/190/8/1652/6140873

To extend previous simulations on the performance of propensity score (PS) weighting and trimming methods to settings without and with unmeasured confounding, Poisson outcomes, and various strengths of treatment prediction (PS c statistic), we simulated studies with a binary intended treatment T as a function of 4 measured covariates.

Unmeasured confounding is a common threat to the validity of observational studies. In practice, confounding bias may arise from both confounders that are completely unmeasured and from confounders that are measured with error.
