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:

- For the categorical data you need to specify the total number of items (e.g., patients, subjects, etc.) in each of the two groups as well as the number of events for each of the two groups.
- For continuous data you only need to specify the numerical values for mean, standard deviation and the number of items (e.g., patients, subjects, etc.) for each of the two groups.

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.

- Major Depressive Disorder Neuroimaging Database - Caudate, left, meta-analysis of neuroimaging data by Matthew J. Kempton.
- Comparative efficacy of NaF and SMFP dentifrices in caries prevention: a meta-analysis overview, a data set used by several researchers for demonstrating meta-analysis methods.
- Sex differences in means and variability on the progressive matrices in university students: a meta-analysis, a study by Paul Irwing and Richard Lynn
- A refined method for the meta-analysis of controlled clinical trials with binary outcome, a data set with categorical data on Cisapride.
