Abstract null null Objective null This study aims to explore the current practice of risk of bias assessment in systematic reviews of behavioral clinical trials published in substance use journals and how assessment results were incorporated into meta-analysis. null null null Study Design and Setting null The authors searched for systematic reviews and meta-analyses of behavioral interventions published from 2016 to 2020 in 40 substance use journals. Two authors independently screened and extrac...

OBJECTIVE To assess the reporting quality of randomised controlled trials (RCTs) with multicentre design, particularly whether necessary information related to multicentre characteristics was adequately reported. STUDY DESIGN AND SETTING Through a search of 4 international electronic databases, we identified multicentre RCTs published in English from 1975 to 2019. Reporting quality was assessed by the CONSORT (Consolidated Standards of Reporting Trials) checklist (37 items) and by a self-designe...

OBJECTIVE Specific survival estimates are needed for the increasing number of colorectal cancer (CRC) survivors. The aim of this population-based study was to determine conditional loss in expectation of life (LEL) due to CRC. STUDY DESIGN AND SETTING All surgically treated patients with CRC registered in the Netherlands Cancer Registry with stage I-III between 1990-2016, were included (N=203,216). Estimates of conditional LEL were predicted using flexible parametric models and the total life ye...

OBJECTIVE To evaluate, across multiple sample sizes, the degree that data-driven methods result in (1) optimal cutoffs different from population optimal cutoff and (2) bias in accuracy estimates. STUDY DESIGN AND SETTING 1,000 samples of sample size 100, 200, 500 and 1,000 each were randomly drawn to simulate studies of different sample sizes from a database (N=13,255) synthesized to assess Edinburgh Postnatal Depression Scale (EPDS) screening accuracy. Optimal cutoffs were selected by maximizin...

Abstract Objectives The Bland and Altman limits of agreement (LoA) method is almost universally used to compare two measurement methods, when the outcome is continuous. The method relies on strong statistical assumptions, which are unlikely to hold in practice. Given the popularity of this simple method, it is timely to explain when it can be safely used and when it should not be used. Study Design and Settings Based on a small sample of simulated data where the truth is known, we illustrate wha...

Abstract Objective Due to the increasing concerns about polypharmacy, there is a growing need for clinical recommendations for drug discontinuation. This requires studies investigating the process on several levels. This paper addresses the methodological problems of drug discontinuation trials (DDTs). To that end, we offer a new typology of research aims and corresponding methodological recommendations for trials evaluating drug discontinuation. Study Design and Setting Multi-stage development ...

OBJECTIVES We aimed to review how 'Risk of Bias In Non-randomised Studies-of Interventions' (ROBINS-I), a Cochrane risk-of-bias assessment tool, has been used in recent systematic reviews. STUDY DESIGN AND SETTING Database and citation searches were conducted in March 2020 to identify recently published reviews using ROBINS-I. Reported ROBINS-I assessments and data on how ROBINS-I was used were extracted from each review. Methodological quality of reviews was assessed using AMSTAR 2 ('A MeaSurem...

OBJECTIVE To identify potential bias in non-inferiority design of published cancer trials, and to provide suggestions for future practice. STUDY DESIGN AND SETTING We systematically searched MEDLINE, Embase and CENTRAL databases (until 17 April 2020) to obtain non-inferiority phase III cancer trials and protocols. Distribution of essential characteristics and study design parameters was compared between trials with and without concluding non-inferiority using multivariable logistic regression. R...
