Comparison Tool

The Comparison Tool provides a matrix view of how different studies compare across arms and outcomes. Access it from the project's Extractions section → Comparison Tool.

Setting Up Comparisons​

From within an extraction's Type3 result section:

  1. Click Add Comparison.
  2. Select the study arms involved (e.g., "Drug A" vs. "Placebo").
  3. Select the outcome (e.g., "Pain score reduction at 6 weeks").
  4. For each measure (e.g., Mean Difference, 95% CI lower, 95% CI upper, p-value):
    • Enter the numerical value.
  5. Check ANOVA if the comparison involves more than two groups.
  6. Repeat for each comparison reported in the paper.

Viewing the Comparison Matrix​

The Comparison Tool renders a matrix with:

  • Rows — Studies (extractions)
  • Columns — Outcomes and measures
  • Cells — The extracted values

This makes it easy to see at a glance which studies report which outcomes and spot missing data.

Managing Measures​

From the results section, you can:

  • Add new measure types to a comparison.
  • Remove measures that are not applicable.
  • Edit existing values.

Click Manage Measures to add or remove measure types globally for the project.
