Acupuncture May Be a Potential Complementary Therapy for Alzheimer’s Disease: A Network Meta-Analysis

Figure 4

Forest plot of treatment differences on the standard normal scale for total effect (a) and ADL (b). The ineffectiveness line (vertical line, X = 1 or X = 0) means an equal ratio. Each horizontal line connects the upper and lower limits of the 95% confidence interval for study, and the length of lines indicates the range of the confidence interval. If the line crossed X = 1 or X = 0, the study was not statistically significant. If the line totally falls on the left side of X = 1 or X = 0 means worse efficacy and the right side for the opposite. The diamond-shaped blocks are the locations corresponding to the OR values. Surface under the cumulative ranking curves for all interventions for total effect (c) and ADL (d). A-Herbal medicine. B-Western medicine. C-Acupuncture. D-Acupuncture + Herbal medicine. E-Acupuncture + Herbal medicine + Western medicine. F-Acupuncture + Western medicine. G-Herbal medicine + Western medicine. Y axis represents cumulative probability and X axis represents rank. Comparing the cumulative probability of the same control ranking, the higher ranking (6⟶1) with a higher cumulative probability means a better curative effect.
