Abstract
This chapter presents an overview of the quantity and quality of clinical research in CAM and publication bias. Descriptive studies and their systematic reviews on CAM, e.g., prevalence and reasons for CAM use, have been widely conducted worldwide. The findings of the efficacy of herbal medicine, traditional Chinese medicine and acupuncture for treating various illnesses, have been highly published. Publications of CAM safety are limited. A number of clinical studies of CAM in treating kidney diseases were lower than other illnesses. Studies of Ayurveda and other CAMs are still lacking. The quality of CAM publications is described based on systematic reviews of assessing CAM publications. Publication bias is explained in terms of selective publications and location bias, language bias and conflict of interest. The mainstream journals are more likely to publish positive findings. Predatory open access and recommendations for assessing predatory journals are addressed in this chapter.
