Study design
Purpose of the study
Allocation to intervention
Randomised controlled trial
Procedure for enrolling a subject and allocating the treatment (allocation concealment procedures)
All participants will be screened for appropriateness by a medical practitioner. If eligible they will be enrolled in the study and randomly allocated to a treatment or placebo group. Medication randomisation is conducted by a computer at a central administration site where the trial medications are also labelled in numbered (coded) containers to maintain concealment for researchers.
Methods used to generate the sequence in which subjects will be randomised (sequence generation)
Randomisation will be conducted by computer randomisation software, performed by a neutral researcher who is not involved in the trial.

Brief summary
The study is a randomised, double-blind, multi-centre clinical trial to evaluate the use of Chinese herbal medicine in the management of endometriosis. Formulated Chinese herbs will be assessed against an inert placebo. Trial participants will be randomly allocated to either Chinese herbal medicine or placebo. Neither participants nor researchers/assessors will have knowledge of the allocation.

It is a prospective clinical study in which participants are reviewed monthly for six months, and three month follow up. Stringent methodology includes an objective laparoscopy diagnosis of endometriosis and suitable outcome measures. The study also includes ensuring participants completing the trial and, facilitating consistent data collection and validity.

The trial will be a multi-centre clinical trial with participants recruited and reviewed at several health centres.

This will be the first clinical trial in Australia combining Chinese herbal medicine, an objective diagnosis (laparoscopy) and a strict methodological protocol.
