Primary Outcomes:
- {'measure': 'Pattern identification', 'description': 'Pattern identification by Body constitution questionnaire(BCQ) BCQ(+) is a questionnaire that is comprised of nineteen questions with one-to-five rating scales, making the range of total score to be between nineteen and ninety-five points with the cut-off score of 30.5 points for Yang-Xu.\n\nBCQ(-) is composed of another set of nineteen questions with the same five-point Likert scales, with the cut-off score of 29.5 points for Yin-Xu.\n\nBCQ(s) consists of twenty-three questions with the same Likert scale cut-off score of 26.5 points for Stasis.', 'timeFrame': 'For 1 year'}

Please estimate the sample size based on the assumption:

        Sample size
        As a preliminary trial for exploring proteomics approach based on pattern identification, we intend to enroll 100 participants.
        
          2.8.1
          LCE groups (LCEX, LCES, and LCEG)
          At least 10 patients will be assigned to each group.
        
        
          2.8.2
          LCR groups (LCRX, LCRS, and LCRG)
          All LCR groups must have the same number of samples. The number of samples in these 3 LCR groups will be set by setting all the control factors other than pattern identification constant.
