We are pleased to announce the findings from Dr Robert Mathie’s latest clinical evidence update:

Total number of randomised controlled trials (RCTs):
2021: 255 RCTs of homeopathic treatments for 136 medical conditions

It is promising to see a slight increase in the volume of trials published per year, i.e. 14 RCTs in 2021, compared to 12 RCTs in 2020.

Double-blind placebo-controlled trials (DB-RCTs):
Considering only DB-RCTs in humans, published in peer reviewed journals (excluding prophylaxis and cross-over studies), the analysis found:

2020: 140 trials on 86 different medical conditions
2021: 148 trials on 88 different medical conditions

 

148 RCTs of homeopathy (end of 2021)


The 8 new DB-RCTs — 2 positive1,2 0 negative and 6 inconclusive3-8 trials — have resulted in a slight shift in the overall balance of evidence as follows:

Positive:         ↓ 1%
Negative:       ↓ 2%
Inconclusive: ↑ 2%
