Data Extraction Form SOP

Design a structured, comprehensive data extraction form tailored to the specific meta-analysis, ensuring all necessary data points are captured systematically.

When to Use

• After PICO, inclusion criteria, and effect size type are determined
• Before beginning full data extraction from included studies
• When standardizing extraction across multiple reviewers

Input

• pico_framework: The structured PICO/PECO framework
• effect_size_type: The chosen effect size metric and calculation methods
• moderator_variables: Pre-specified moderator variables for heterogeneity investigation

Output

A complete data extraction form with field definitions, coding instructions, and examples for each variable.
