In this paper , the statistic significance and clinical application of forest plots in a meta-analysis have been fully discussed. If the horizontal line represents the 95% confidence interval of the indexes including odds ratio, relative risk, weighted mean difference, and standard mean difference crosses the vertical line, the effect of test group is not signficant with that of control group; if the horizontal line lies to the right of the vertical line, it indicates that the test group is significantly effctive. If the horizontal line lies to the left of the vertical line, it indicates that the control group is more effective.

对Meta-分析的森林图的统计学意义和临床应用做了较为详细的解释：当统计指标比值比、相对危险度、加权均数差和标准化均数差的95%可信区间横线与森林图的无效线(横坐标刻度为1或0)相交时，试验组的效应量等于对照组，试验因素无效；当其95%可信区间横线不与森林图的无效线相交且落在无效线右侧时，试验组的效应量大于对照组；当其95%可信区间横线不与森林图的无效线相交且落在无效线左侧时，试验组的效应量小于对照组。
