Meta-Analytical Data Extraction enables you to gather quantitative data from underlying studies. In short, after configuring your Interventions and Data Elements on the Configure MA Extraction page, you can extract dichotomous, categorical, or continuous data across any number of timepoints from all included studies.
In order to perform meta-analytical extraction, you first need to Configure Interventions and Data Elements, which you do from the Configure MA Extraction page in order to reuse the tag hierarchy. Interventions correspond to the types of therapies/treatments/medications etc. that were compared across the articles and appear as purple in the Tag Hierarchy. Data Elements refer to all other relevant data from the article that will be extracted for meta-analytical data and appear as gold in the Tag Hierarchy. Note: Only one hierarchy can be designated as your Intervention hierarchy, but any node in your hierarchy can be configured as a Data Element. There is no requirement, however, that every tag be configured as a data element!
Once you have configured your Interventions and Data Elements, you are ready to extract data from all included studies in the nest. Steps for MA Extraction: 1. Navigate to Extraction Select “MA Extraction” from the menu: Alternatively, you can Extract MA data from the “MA Extract” tab in Inspector. See here for details on how to get to the...
This page describes the computational methods used in Quantitative Synthesis (QNS). Data Analyzed Any study included (adjudicated, in dual screening) during Screening and with Meta-Analytical extraction marked “Complete” is analyzed on QNS. If dual extraction is configured for the nest, only adjudicated data is analyzed in QNS. Analyses Summary (Pooled Estimates) Any study with one or more arms extracted are analyzed...
