Note: as some subjects presented several TCM constitutions, i.e., they met the criteria of two or more TCM constitutions, they were included in the table as two TCM constitutions. For example, if a subject was identified as both Qi-deficiency constitution and phlegm constitution, the patient was included in the Qi-deficiency group as well as the phlegm group. If the subject did not meet the criteria of “Yes” for that constitution type, they were not included in the statistical analysis.
