Are we drawing the right conclusions from randomised placebo-controlled trials? A post-hoc analysis of data from a randomised controlled trial

open access: yesBMC Medical Research Methodology, 2009
Background Assumptions underlying placebo controlled trials include that the placebo effect impacts on all study arms equally, and that treatment effects are additional to the placebo effect.

Age and Sex as Moderators of the Placebo Response - An Evaluation of Systematic Reviews and Meta-Analyses across Medicine

open access: yesGerontology, 2014
Predictors of the placebo response (PR) in randomized controlled trials (RCT) have been searched for ever since RCT have become the standard for testing novel therapies and age and gender are routinely documented data in all trials irrespective of the ...

Oxytocin Improves Autistic Behaviors by Positively Shifting GABA Reversal Potential via NKCC1 in Early‐Postnatal‐Stage

open access: yesAdvanced Science, EarlyView.
New research reveals that oxytocin signaling during the early postnatal period is critical for regulating brain development and social behavior. Selectively suppressing oxytocin neurons by chemogenetic method shows that early—but not late—disruption leads to autism‐like behaviors.

Gamma oscillations and application of 40‐Hz audiovisual stimulation to improve brain function

open access: yesBrain and Behavior, Volume 12, Issue 12, December 2022., 2022
Abstract Background Audiovisual stimulation, such as auditory stimulation, light stimulation, and audiovisual combined stimulation, as a non‐invasive stimulation, which can induce gamma oscillation, has received increased attention in recent years, and it has been preliminarily applied in the clinical rehabilitation of brain dysfunctions, such as ...

Efficient, Doubly Robust Estimation of the Effect of Dose Switching for Switchers in a Randomised Clinical Trial [PDF]

open access: yesarXiv, 2020
Motivated by a clinical trial conducted by Janssen Pharmaceuticals in which a flexible dosing regimen is compared to placebo, we evaluate how switchers in the treatment arm (i.e., patients who were switched to the higher dose) would have fared had they been kept on the low dose.

Improving Adult Vision Through Pathway‐Specific Training in Augmented Reality

open access: yesAdvanced Science, EarlyView.
Traditional perceptual training approaches are limited by stimulus specificity, treatment efficacy, and patient compliance. A novel altered reality (AR) method is developed to enhance pathway‐specific functions in human adults while performing everyday activities.

Does going abroad lead to going green? Firm outward foreign direct investment and domestic environmental performance

open access: yesBusiness Strategy and the Environment, Volume 32, Issue 1, Page 484-498, January 2023., 2023
Abstract This study examines whether and how outward foreign direct investment (OFDI) affects firms' domestic environmental performance. We use both the reverse knowledge transfer and resource crowding perspectives to predict the association. Using a sample of Chinese firms, we find that firms' environmental performance improves after the initiation of

Decoding Blastocystis‐Driven Mechanisms in Gut Microbiota and Host Metabolism

open access: yesAdvanced Science, EarlyView.
Blastocystis, a prevalent gut microbe, interacts with the host through metabolic and immune pathways, influencing cardiometabolic health. This perspective explores its role in modulating short‐chain fatty acid production, tryptophan metabolism, and immune signaling, potentially impacting cholesterol absorption, glucose metabolism, and vascular health ...

Equivalence of regression curves sharing common parameters [PDF]

open access: yesarXiv, 2019
In clinical trials the comparison of two different populations is a frequently addressed problem. Non-linear (parametric) regression models are commonly used to describe the relationship between covariates as the dose and a response variable in the two groups.
