TDS: Total Dyspepsia Symptom; SDS: Single Dyspepsia Symptom; VAS: Visual Analogue Scale; NDI-K: Nepean Dyspepsia Index-Korean Version; FD-QoL: Functional Dyspepsia-Related Quality of Life; SQDQ: Spleen Qi Deficiency Questionnaire.
Treatment group includes gallbladder and bladder body groups.
Change rate is defined as the value obtained by subtracting the value of 8 weeks from the value of baseline and dividing it by the value of baseline.
Values were analyzed by Pearson's chi-squared test for categorical variables and independent two-sample t-test as parametric statistical test or Mann–Whitney U test as nonparametric statistical test for continuous variables.
Continuous variables are presented as mean (standard deviation).
P value < 0.05 is regarded as statistically significant.
