BACKGROUND The CONSORT statement is intended to improve reporting of randomised controlled trials and focuses on minimising the risk of bias (internal validity). The applicability of a trial's results (generalisability or external validity) is also important, particularly for pragmatic trials. A pragmatic trial (a term first used in 1967 by Schwartz and(More)
If randomized controlled trials (RCTs) are to fulfill their potential to allow health care providers to make informed inferences about the validity of the trials upon which they base their clinical practice, then the reporting of key methodological factors must improve. The revised Consolidated Standards for Reporting Trials (CONSORT) were developed to(More)
Herbal medicinal products are widely used, vary greatly in content and quality, and are actively tested in randomized, controlled trials (RCTs). The authors' objective was to develop recommendations for reporting RCTs of herbal medicine interventions, based on the need to elaborate on the 22-item CONSORT (Consolidated Standards of Reporting Trials)(More)
BACKGROUND Low-back pain (LBP) is a common condition and imposes a substantial economic burden upon people living in industrialized societies. A large proportion of people with chronic LBP use complementary and alternative medicine (CAM), visit CAM practitioners, or both. Several herbal medicines have been purported for use in treating people with LBP. This(More)
BACKGROUND A case report is a narrative that describes, for medical, scientific, or educational purposes, a medical problem experienced by one or more patients. Case reports written without guidance from reporting standards are insufficiently rigorous to guide clinical practice or to inform clinical study design. PRIMARY OBJECTIVE Develop, disseminate,(More)
BACKGROUND Public interest in herbal medicines has generated an increasing number of trials evaluating their efficacy. Trials with poor methodologic quality have exaggerated estimates of treatment effect, and incomplete reporting of trials causes difficulties in assessing trial methodologic quality. The objective of this project was to examine the quality(More)
BACKGROUND Critics of systematic reviews have argued that these studies often fail to inform clinical decision making because their results are far too general, that the data are sparse, such that findings cannot be applied to individual patients or for other decision making. While there is some consensus on methods for investigating statistical and(More)
BACKGROUND While there is some consensus on methods for investigating statistical and methodological heterogeneity, little attention has been paid to clinical aspects of heterogeneity. The objective of this study is to summarize and collate suggested methods for investigating clinical heterogeneity in systematic reviews. METHODS We searched databases(More)
BACKGROUND We aimed to determine if specialist journals implement specific Consolidated Standards for Reporting Trials (CONSORT) recommendations to the same extent as general medical journals. METHODS Analysis of random controlled trials (RCTs) in five general medical journals (n=100) and 10 specialist journals (n=100), all endorsing CONSORT. We evaluated(More)
Herbal medicinal products (HMPs) are used in a variety of oral and topical forms for the treatment of osteoarthritis. The aim of this study was to update a previous systematic review published in 2000. We searched electronic databases (MEDLINE, EMBASE, CISCOM, AMED, CINAHL, Cochrane registers) to June 2007, unrestricted by date or language, and included(More)
