 ====== Data Extraction ======
-Data extraction is the last major step to complete your Nest. Data must be extracted correctly in order to ensure accurate results.
+Once you have [[:wiki:autolit:extraction:configure|configured]] your Interventions and Data Elements, you are ready to extract data from all included studies in the nest.
