Figure 2

The annual records of Chinese-language articles about TCM Zheng classification in 2 categories. The data were obtained from the SinoMed database (until December 11, 2011). The statistics are based on scanning studies as to whether they contain a disease name in the framework of Western medicine. The count of “independent Zheng” increases by one if a study does not contain a disease name, and the count of “Zheng in disease” increases by one if the study contains one or more disease names.
