I took a look at the study you mentioned. It was done by a group of South Korean researchers. If you read the study they had two different groups - one group they used CV 4, CV 12, ST 36, and SP 6 points that "improve physical function and gynecological disease", the other group used GV 4, UB 23, CV 4, and CV 6 drawn from other works on treatment gynecological conditions. The results were a reduction from 40-60% with no incredible difference between the two treatment groups.
They used indirect moxibustion. "Four weeks of treatment was given, with four treatments per week during the first 2 weeks and three treatments per week thereafter. Five moxibustion capsules were used at each point in a single session. The moxibustion we used is formulated as a disposable adhesive (Kangwha minimoxa, Ewahdang, Seoul, South Korea), and it is composed of a moxa pillar that is attached to the base of the device. The total length of the moxibustion device is 25 mm, of which 18 mm constitutes the moxa pillar."
I still stand by what I said earlier - this wouldn't be my first choice and personally I think you can do better than a 40-60% improvement rate with other options. For cases that do not respond, however, it may be worth some further testing.
