Systematic reviews are a type of literature review that uses systematic methods to identify, select, and critically appraise primary research literature relevant to a specific research question. The research question for a systematic review is usually defined in terms of one or more specific PICO elements—population, intervention, comparison, and outcome. A systematic review is different from a traditional, or narrative, literature review in that it uses explicit, systematic methods to identify relevant research, to appraise the quality of that research, and to synthesize the findings in a way that minimizes bias.
One of the challenges of conducting a systematic review is keeping track of the large number of studies that are identified in the literature search. It is not uncommon for a systematic review to include hundreds or even thousands of studies. One way to keep track of the studies is to create a database of the studies that are identified. The database can be used to store information about each study, such as the title, author, journal, year of publication, and a brief summary of the findings.
Another way to keep track of the studies is to create a table that includes all of the studies that are relevant to the PICO question. The table can be used to track the studies by their PICO elements, and to identify which studies are included in the review and which are not.
Once the studies have been identified and categorized, the next step is to critically appraise the studies. This involves assessing the quality of the studies and determining whether or not the findings are reliable. The appraised studies are then synthesized to create a summary of the evidence.
Systematic reviews are a powerful tool for conducting research and for making decisions about healthcare. However, they can be time-consuming and challenging to conduct. It is important to use systematic and explicit methods to keep track of the studies that are identified in the literature search, to appraise the quality of the studies, and to synthesize the findings.

How do you deal with duplicate records?
There are a few ways to deal with duplicate records:
1. Use a unique key: This will ensure that each record is unique and no duplicates will be allowed.
2. Use a hash: This will calculate a unique value for each record and store it in a hash table. Duplicates will be allowed, but they will be easy to spot.
3. Use a fingerprint: This will calculate a unique value for each record based on its content. Duplicates will be allowed, but they will be easy to spot.
