Randomised controlled trials in homeopathy

Criteria and methods for data extraction

This section contains references to full papers of randomised and controlled trials (RCTs) of homeopathy (treatment or prevention, placebo-controlled design or otherwise) that have been published in the peer-review literature in any country and in any language from 1950 to 2013 inclusive. Any form of homeopathy (individualised or non-individualised) was eligible for inclusion. RCTs were primarily categorised as placebo-controlled or non-placebo-controlled. For the present analysis we do not distinguish between treatment trials and prevention trials. The analysis is based on our systematic review of the world’s RCT literature in homeopathy [Mathie RT, Hacke  D, Clausen J, et al. (2013). Randomised controlled trials of homeopathy in humans: characterising the research journal literature for systematic review. Homeopathy; 102: 3–24].

Note on statistical significance
A minority of placebo-controlled trials in homeopathy have defined a relevant threshold for clinical importance, with consequent absence of prospective power calculation. On this web page, therefore, positive or negative findings have been described consistently in statistical terms only.

A statistically conclusive trial result requires that the 95% confidence interval of the mean difference in outcome measure does not include 0 (or P<0.05); a statistically non-significant trial result is one in which the confidence interval includes 0 (or P>0.05). An RCT reporting statistically significant findings is labelled either ‘positive’ or ‘negative’, depending on whether the homeopathy group was superior or inferior to control in at least one main outcome of no more than three presented in the paper. Statistically non-significant trials are described as ‘non-conclusive’.

Overall summary of trial findings, 1950–2013

During this period, there were 188 peer-reviewed RCT papers published in homeopathy. For any paper that reports a trial comprising more than two groups of participants, we present here just one inter-group comparison and in the following hierarchy: placebo-controlled in favour of non-placebo-controlled; individualised homeopathy in favour of non-individualised homeopathy. The majority (153; 81%) of the 188 papers reported placebo-controlled studies, whilst the remaining 35 (19%) reported studies with a non-placebo comparator (e.g. usual medical care). Only 63 RCTs (34%) of the 188 papers have studied individualised homeopathy (46 of those 63 were placebo-controlled); each of the other 125 papers (66%) has studied non-individualised homeopathy (i.e. selected a single homeopathic medicine for investigation).

Of the 188 papers in total, 82 (44%) reported positive findings; 10 (5%) were negative; 89 (47%) were non-conclusive; 7 (4%) contained non-extractable data.

The 188 papers represent research in a total of 100 different medical conditions. In 33 of those conditions, there has been replicated research (i.e. there have been two or more trials); for each of the other 67 conditions, there are singleton RCTs. No account is taken here of the intrinsic quality of the research; this important factor is included in our ongoing programme of systematic reviews.

Direction of RCT evidence per medical condition

A score of +1 is given to a positive RCT0 to a non-conclusive RCT–1 to a negative RCT.

The overall direction of RCT evidence for each medical condition relates to the sum of the scores derived from the RCT research for that particular condition:

Sum of +3 or more: Clearly positive direction of evidence
Sum of +2 or +1: Tentatively positive direction of evidence
Sum of 0: Non-conclusive direction of evidence
Sum of –1 or –2: Tentatively negative direction of evidence
Sum of –3 or less: Clearly negative direction of evidence.

This method of summarising direction of evidence in sets of RCTs is similar in essence to that adopted previously [Ernst E, Pittler MH, Wider B (2006). The Desktop Guide to Complementary and Alternative Medicine; an evidence-based approach. Mosby Elsevier]. It is not meant as a replacement for formal assessment procedures, such as systematic review and/or meta-analysis, which determine a trial’s intrinsic quality and/or the size of treatment effect for a specified outcome measure.

The summary method is intended to give an overall impression about the current nature of the RCT evidence per medical condition, pending more formal systematic review. Such formal review would also take account of whether evidence has been reported by independent research groups.

Thus, of the medical conditions for which RCTs have been carried out in homeopathy, 44% have an overall balance of positive evidence, 5% have a balance of negative evidence, and 47% are non-conclusive either way.

The above figures have similarities to data obtained from an analysis of 1016 systematic reviews of RCTs (and therefore of many more than that number of RCTs in total): 44% of the reviews concluded that the interventions studied were likely to be beneficial (positive), 7% concluded that the interventions were likely to be harmful (negative), and 49% reported that the evidence did not support either benefit or harm (non-conclusive).
