What the study found
The one registered ratio trial finished in March 2025 and went quiet
It set 40 to 1 against 3.6 to 1 in 30 women, and it was registered by the company selling the branded 40:1 product. Nothing has been posted. Of 62 registered myo-inositol trials in polycystic ovary syndrome, 2 have posted results and 33 completed without any.
The caveat · Many publish without posting back
A registry entry records that a trial was declared, not what it found, so none of these counts is evidence about how inositol works. Trials often publish in journals without ever posting back to the registry, so a raw non-posting count overstates true non-reporting. This registry is US-centred and under-covers the Italian and Indian trials that dominate this field.
