This webservice will download a specified page from the Brede Wiki. The page should contain a comma-separated values (CSV) file with information for a meta-analysis. Study effect sizes and meta-analytic effect sizes will be computed.

The CSV file should provide information about the two groups: "experimentals" and "controls". The information you need to supply depends on whether your data is categorical (binary) or continuous:

You will usually need to specify the column names used for the data, but an automated guess will be performed if columns are not specified.


M: mean, SD: standard deviation of data, SDpooled: Pooled standard deviation of data, N: number of data (subjects, etc.), MD: mean difference, SMD: standardized mean difference, CI: 95% confidence interval.
