A random sample with 41 TCM systematic reviews was selected from a database developed in a previous study [10] . Of which, only 9 reviews were written in English, and the majority (78%) was published in Chinese journals . The sample included 35 paper-based reviews and 6 Cochrane reviews; there was only one updated Cochrane review. According to the International Classification of Diseases 10 (ICD-10), the topics of the reviews ranged across 9 systems, and mainly focused on diseases of circulatory system Evidence-Based Complementary and Alternative Medicine 3 (15 SRs or 37% of the sample, such as stroke and other cardiovascular diseases), infectious and parasitic diseases (7 SRs, like HBV, SARS), genitourinary system (5 SRs, such as ectopic pregnancy), digestive system (4 SRs, like ulcerative colitis), nervous system (3 SRs, such as Parkinson's disease), and musculoskeletal system and connective tissue (3 SRs, osteoporosis). The number of pages of included TCM SRs ranged widely from 2 to 80 with a median of 6 pages, of which, Cochrane systematic reviews had more pages than non-Cochrane reviews (P < 0.001), with medians of 31 (range: 16-80) and of 5 (range: 2-11), respectively. Less than half of the reviews (41.5%) were presented by clinicians.
