Evidence-based Review of the Pharmacoeconomic Evaluation Technical Essentials of Chinese Material Medica in Treating Pelvic Inflammatory Disease Sequela (Chronic Pelvic Inflammation) / 世界科学技术-中医药现代化

Pelvic inflammatory disease sequela (chronic pelvic inflammation) is one of the diseases that affect women's health conditions, and leads to large economic burden. Chinese Material Medica (CMM) plays an impor-tant role in treating pelvic inflammatory disease sequela (chronic pelvic inflammatory). However, due to the lack of Evidence-based Pharmacoeconomic Evaluation Technical Essentials of CMM in Treatment of Pelvic Inflamma-tory Disease Sequela (Chronic Pelvic Inflammatory), non-standard phenomenon often appears in the research liter-ature, such as the selection of research methods, viewpoint of research, determination of cost, effect and utility. Thus, the publish of Evidence-based Pharmacoeconomic Evaluation Technical Essentials of CMM in Treatment of Pelvic Inflammatory Disease Sequela (Chronic Pelvic Inflammatory) is essential for the pharmacoeconomic evalua-tion of CMM in treating pelvic inflammatory disease sequela (chronic pelvic inflammatory).
