^a R-square = 0.1893 and adjusted R-square = 0.1889 in a multiple linear regression model that was adjusted for length of stay, age, sex, insurance type, hospital type, region, hypertension, coronary heart disease, diabetes, chronic pulmonary disease, peripheral vascular disease, other neurological diseases, rheumatoid arthritis, and peptic ulcer disease. The baseline represents the TCM cost for a female with Urban Resident Basic Medical Insurance admitted to a primary hospital and non-TCM hospital in the western region without the above-observed comorbidities. TCM: traditional Chinese medicine; UEBMI: Urban Employee Basic Medical Insurance scheme; URBMI: Urban Resident Basic Medical Insurance scheme.
