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 .
AIM Our objective was to investigate which assessment s of pain are more commonly used in clinical trials on CPP .
Randomized trial of leuprolide versus continuous oral contraceptives in the treatment of endometriosis-associated pelvic pain.
OBJECTIVE To compare the efficacy of leuprolide and continuous oral contraceptives in the treatment of endometriosis-associated pain . DESIGN Prospect i ve , r and omized , double-blind controlled trial . SETTING Academic medical centers in Rochester , New York , and Boston , Massachusetts . PATIENT(S ) Forty-seven women with endometriosis-associated pelvic pain . INTERVENTION(S ) Forty-eight weeks of either depot leuprolide , 11.25 mg IM every 12 weeks with hormonal add-back using norethindrone acetate 5 mg orally , daily ; or a generic monophasic oral contraceptive ( 1 mg norethindrone + 35 mg ethinyl estradiol ) given daily . MAIN OUTCOME MEASURE(S ) Biberoglu and Behrman ( B&B ) pain scores , numerical rating scores ( NRS ) , Beck Depression Inventory ( BDI ) , and Index of Sexual Satisfaction ( ISS ) . RESULT ( S ) Based on enrollment of 47 women r and omized to continuous oral contraceptives and to leuprolide , there were statistically significant declines in B&B , NRS , and BDI scores from baseline in both groups . There were no significant differences , however , in the extent of reduction in these measures between the groups . CONCLUSION ( S ) Leuprolide and continuous oral contraceptives appear to be equally effective in the treatment of endometriosis-associated pelvic pain
