Modelling multiple outcomes to improve the detection of causal mediation effects in complex intervention trials

چکیده
Aim In a trial to increase physical activity in sedentary adults, there was no evidence of effect on the primary outcome, though large significant effects amongst eight related SF36 measures of general health [1]. How could such differences arise? Could they be: a true effect mediated through receiving the intervention, another systematic effect such as self-reporting bias, and/or chance? The aim was to develop reliable methods to investigate whether effects of the intervention on the SF36 outcomes were mediated through truly receiving the intervention delivered in intervention sessions.

Understanding how pain education causes changes in pain and disability: protocol for a causal mediation analysis of the PREVENT trial.
INTRODUCTION Pain education is a complex intervention developed to help clinicians manage low back pain. Although complex interventions are usually evaluated by their effects on outcomes, such as pain or disability, most do not directly target these outcomes; instead, they target intermediate factors that are presumed to be associated with the outcomes. The mechanisms underlying treatment effec...
متن کاملCausal inference techniques for trials of complex interventions
A statistical framework based on potential outcomes has been developed in which causal effects can be unambiguously defined, and the assumptions needed for their estimation clearly stated. This has also led to the development of new statistical methods that are especially designed for making causal inferences from non-randomised exposures under transparent, less restrictive and more plausible a...

INTRODUCTION Low back pain (LBP) and knee osteoarthritis (OA) are highly prevalent and disabling conditions that cause societal and economic impact worldwide. Two randomised controlled trials (RCTs) will evaluate the effectiveness of a multicomponent lifestyle intervention for patients with LBP and knee OA who are overweight or obese. The key targets of this intervention are to improve physical...
متن کاملDesigning trials of complex interventions for efficacy and mechanisms evaluation
Objectives There have been recent developments in statistical methods for assessing the mechanisms through which a complex intervention acts, with particular applications in mental health trials. This literature has focused on causal mediation analysis, which differs from statistical mediation analysis by its explicit acknowledgement and exposition of the necessary assumptions, particularly tha...
متن کاملThe Effect of Lifestyle Intervention on Pregnancy and Birth Outcomes on Obese Infertile Women: A Systematic Review and Meta-Analysis
Background: Obesity has been associated to negative effects on natural fertility and a worse prognosis when assisted reproduction techniques are performed. Patients attending for fertility treatments are often advised to optimize their weights to improve outcomes. There are doubts about how effective are weight-loss interventions for improving fertility in women who are overweight or obese. Mat...
