Sign Up to like & getrecommendations! Published in 2022 at "JAMA cardiology"
DOI: 10.1001/jamacardio.2021.6000
Abstract: Importance Autonomic neuromodulation provides therapeutic benefit in ventricular tachycardia (VT) storm. Transcutaneous magnetic stimulation (TcMS) can noninvasively and nondestructively modulate a patient's nervous system activity and may reduce VT burden in patients with VT storm.… read more here.

Weak and pleiotropy robust sex‐stratified Mendelian randomization in the one sample and two sample settings

DOI: 10.1002/gepi.22512
Abstract: Mendelian randomization (MR) leverages genetic data as an instrumental variable to provide estimates for the causal effect of an exposure X on a health outcome Y that is robust to confounding. Unfortunately, horizontal pleiotropy—the direct… read more here.

DOI: 10.1002/sim.8093
Abstract: As randomization methods use more information in more complex ways to assign patients to treatments, analysis of the resulting data becomes challenging. The treatment assignment vector and outcome vector become correlated whenever randomization probabilities depend… read more here.

DOI: 10.1002/sim.8577
Abstract: Randomization-based interval estimation takes into account the particular randomization procedure in the analysis and preserves the confidence level even in the presence of heterogeneity. It is distinguished from population-based confidence intervals with respect to three… read more here.

DOI: 10.1007/s10461-018-2048-y
Abstract: Identifying individuals with recent HIV infection is critical to research related to viral reservoirs, outbreak investigations and intervention applications. A multi-assay algorithm (MAA) for recency of infection was used in conjunction with self-reported date of… read more here.

DOI: 10.1007/s10648-020-09549-7
Abstract: Previous simulation studies of randomization tests applied in single-case educational intervention research contexts have typically focused on A-to-B phase changes in means/levels. In the present simulation study, we report the results of two multiple-baseline investigations,… read more here.

DOI: 10.1007/s10654-019-00578-3
Abstract: In recent years, epidemiologists have increasingly sought to employ genetic data to identify ‘causal’ relationships between exposures of interest and various endpoints – an instrumental variable approach sometimes termed Mendelian randomization. However, this approach is… read more here.

DOI: 10.1007/s11245-018-9542-8
Abstract: A key role in inference is played by randomization, which has been extensively used in clinical trials designs. Randomization is primarily intended to prevent the source of bias in treatment allocation by producing comparable groups.… read more here.
