We are pleased to share the results of a recent collaboration with Dr Robert Mathie to update his analysis of randomised controlled trials of homeopathy.

The findings from the 5 year update from 2014-2019 are as follows:

Total number of randomised controlled trials

2014: 189 trials of homeopathic treatment for 100 medical conditions
2019: 221 trials of homeopathic treatment for 115 medical conditions

Placebo-controlled trials only

2014: 104 trials on 63 medical conditions
2019: 129 trials on 77 medical conditions

When considering the balance of positive, negative and inconclusive studies, it is interesting to observe the following shifts in the evidence base for homeopathy over this 5 year period:

Positive trials                Up from 41% to 45%
Negative trials              Down from 5% to 4%
Inconclusive trials        Down from 54% to 51%
