The part we've all been waiting for! It's time to search!
Screening your studies by title and abstract:

You will work with Drs. Puga and Richardson to create tables or forms for recording data. You may hear this referred to as a "Synthesis Table."
It's an important step because it allows "apples to apples" comparison and will more easily inform your next step, which is Data Synthesis.
Often, this step is completed in tandem with the full-text screen. As you read full-text articles to determine suitability for inclusion, you will also code them.
If you are interested in creating a meta-analysis, please consider the following:
Blinded reviewers (ideally two) will extract the data.
There are 2 types of synthesis:
