RESULTS The instruments most frequently used were single-item VAS and Biberoglu and Behrman pain score , while multidimensional inventories were used in few studies .
The results of clinical studies in CPP are more frequently based on one-dimensional measurements .
RATIONALE Many types of  pain assessment are available to research ers carrying out clinical trials in chronic pelvic pain ( CPP ) , ranging from a single-item scale to multidimensional inventories .

Low-dose danazol after combined surgical and medical therapy reduces the incidence of pelvic pain in women with moderate and severe endometriosis.
The most effective therapy for endometriosis is a matter for debate . The aim of the present r and omized study was to evaluate the efficacy of low doses of danazol on recurrence of pelvic pain in patients with moderate or severe endometriosis , who had undergone laparoscopic surgery and 6 months of gonadotrophin-releasing hormone analogue ( GnRHa ) therapy .  After surgery , 28 patients with moderate or severe endometriosis underwent therapy for 6 months with GnRHa i. m. every 4 weeks . They were then r and omized into two groups : group A ( 14 subjects ) was treated with 100 mg/day danazol for 6 months ; group B ( 14 subjects , control )  did not receive any type of therapy . After 12 months of treatment , group A had a significantly ( P < 0.01 ) lower pain score than group B. There was no significant difference between the groups in oestrogen concentrations , bone mineral density or side-effects . The results suggest that low-dose danazol therapy reduces recurrence of pelvic pain in patients with moderate or severe endometriosis , treated surgically , and has few or no metabolic side-effects
