为什么使用CMA软件
我们是CMA软件国内正式授权经销商。
对于研究者
CMA极其容易学习和使用，有着清楚而且交互式的操作界面。交互式指导将带领您穿越分析中的所有步骤，让新用户在几分钟内就可以入门分析过程。
对于统计学家
CMA是由多名公认的在元分析(meta-analysis)领域的专家共同开发的，他们都在US和UK。软件包含了大量的用于数据输入，分析和显示的高级选项。
对于学校老师
通过CMA，元分析的逻辑变得栩栩如生。使用程序可以帮助解释复杂问题，比如研究权重对于组合效应的影响，异质性(heterogeneity)的含义,或者固定效应和随机效应之间的差异。

技术规范
Data entry
 Enter data in 100+ formats.
Enter data using a spreadsheet interface.
Enter data for each study in its own format. For example, enter data for one study as number of events and sample size, for another study as odds ratio and confidence interval, and so on.
Include multiple study designs in the same analysis. Enter data from studies that used independent groups, paired/matched designs, or crossover trials. The program will compute the standard errors for each, and allow you to merge the different designs in the same analysis.
Include data from prospective and retrospective trials in the same analysis.
Mix and match continuous, binary, and correlational data within the same analysis. The program will convert among odds ratios, standardized mean differences, and correlations.
Data structure
Independent subgroups within studies
Multiple outcomes within studies
Multiple time-points within outcomes
Multiple comparisons (Placebo vs A and Placebo vs B) within studies
Computational options
Computational models for one group: Fixed effect, random effects
Computational models for Anova: Fixed effect, mixed models, fully random effects
Computational models for meta-regression: Fixed effect, method of moments, unrestricted maximum likelihood
Inverse variance, Mantel Haenszel, Peto
Includes options to use the same computational algorithms as other programs such as RevMan or Stata.
Data import
Import data from other programs, including STATA, Revman, Excel, and SPSS.
Special purpose analyses
Cumulative analysis. Runs the analysis k times, adding an additional study with each iteration, to show how the treatment effect changed over time.
Sensitivity analysis. Runs the analysis k times, each time removing one study, to show that study’s impact on the combined effect.
High-resolution plots
Create forest plots with one click.
Specify the symbols for studies, subgroups, and combined effects. Make the symbol a constant size or proportional to study weight.
Modify colors globally or for each element of the plot. Set templates for formats and color schemes.
Export directly to Word or PowerPoint or save as file.
Publication bias
Funnel plots using precision
Funnel plots using standard error
Fail-Safe N
Orwin’s Fail-Safe N
Trim and Fill
Rank correlation test
Regression test
Program produces statistics, plots, and a detailed text report for each of the publication bias procedures.
Effect size measures
For studies that look at treatment effects or other effect sizes the program will compute the odds ratio, risk ratio, risk difference, standardized mean difference (d), bias-corrected standardized mean difference (Hedges’s g), raw mean difference, correlation, hazard ratio, rate ratio, and more.
For studies that look at events or means for one group the program will compute the risk, the rate, or the mean.
For other measures (e.g. regression coefficients) the program will work with generic indices. This is available both for raw values and for log values.
