Chinese Herbal Medicine Liu Jun Zi Tang and Xiang Sha Liu Jun Zi Tang for Functional Dyspepsia: Meta-Analysis of Randomized Controlled Trials

Table 2

Odds ratios (ORs) and summary OR for Liu Jun Zi Tang (LJZT) trials. OR and their 95% confidence intervals are presented with weighting in a fixed effect model. OR > 1.0 indicates that the symptomatic improvement of functional dyspepsia is higher in the LJZT group than that in prokinetic drugs group.
