A systematic review of randomised controlled trials (RCTs) of veterinary homeopathy has not previously been undertaken. Using Cochrane methods, this review aims to assess risk of bias and to quantify the effect size of homeopathic intervention compared with placebo for each eligible peer-reviewed trial. Judgement in seven assessment domains enabled a(More)
BACKGROUND Meta-analysis of randomised controlled trials (RCTs) of veterinary homeopathy has not previously been undertaken. For all medical conditions and species collectively, we tested the hypothesis that the outcome of homeopathic intervention (treatment and/or prophylaxis, individualised and/or non-individualised) is distinguishable from corresponding(More)
BACKGROUND A rigorous and focused systematic review and meta-analysis of randomised controlled trials (RCTs) of individualised homeopathic treatment has not previously been undertaken. We tested the hypothesis that the outcome of an individualised homeopathic treatment approach using homeopathic medicines is distinguishable from that of placebos. METHODS(More)
INTRODUCTION A new programme of systematic reviews of randomised controlled trials (RCTs) in homeopathy will distinguish important attributes of RCT records, including: placebo controlled versus other-than-placebo (OTP) controlled; individualised versus non-individualised homeopathy; peer-reviewed (PR) versus non peer-reviewed (NPR) sources. AIMS (a) To(More)
BACKGROUND To date, our programme of systematic reviews has assessed randomised controlled trials (RCTs) of individualised homeopathy separately for risk of bias (RoB) and for model validity of homeopathic treatment (MVHT). OBJECTIVES The purpose of the present paper was to bring together our published RoB and MVHT findings and, using an approach based on(More)
BACKGROUND No systematic review has previously been carried out on randomised controlled trials (RCTs) of veterinary homeopathy in which the control group was an intervention other than placebo (OTP). For eligible peer-reviewed RCTs, the objectives of this study were to assess the risk of bias (RoB) and to quantify the effect size of homeopathic(More)
The database HomBRex (Homeopathy Basic Research experiments) was established in 2002 to provide an overview of the basic research already done on homeopathy (http://www.carstens-stiftung.de/hombrex). By this means, it facilitates the exploration of the Similia Principle and the working mechanism of homeopathy. Since 2002, the total number of experiments(More)
The Similia Principle, the basis of homeopathy, implies that substances initiating symptoms when applied to healthy biological systems can be utilized as remedies to treat a diseased system with similar symptoms. Depending whether the remedy substance was of the same type as the etiologic agent, treatment is classified as either homologous or heterologous.(More)
BACKGROUND Veterinary homeopathy has led a somewhat shadowy existence since its first introduction. Only in the last three decades has the number of clinical trials increased considerably. This literature is generally not well perceived, which may be partly a consequence of the diffuse and somewhat inaccessible nature of some of the relevant research(More)
Die Einbeziehung von Patienten in Forschungsprojekte („partizipative Forschung“) ermöglicht es den Forschern, wertvolle zusätzliche Einblicke in die untersuchte Thematik zu erhalten. Die aktive Beteiligung von Patienten wird als wichtiger Faktor dafür gesehen zu gewährleisten, dass Forschungsprojekte die Ausgangspunkte für echte Verbesserungen im(More)
