        Step 1: Identify a Research Field
        The first step in writing a systematic review paper is to identify a research field. This involves selecting a specific area of study that you are interested in and want to explore further.
        
        Step 2: Generate a Research Question
        Once you have identified your research field, the next step is to generate a research question. This question should be specific, measurable, achievable, relevant, and time-bound (SMART).
        
        Step 3: Create a Protocol
        After generating your research question, the next step is to create a protocol. A detailed plan of how you will conduct your research, including the methods you will use, the data you will collect, and the analysis you will perform.
        
        Step 4: Evaluate Relevant Literature
        The fourth step is to evaluate relevant literature. This involves searching for and reviewing existing studies related to your research question. You should critically evaluate the quality of these studies and identify any gaps or limitations in the current literature.
        
        Step 5: Investigate Sources for Answers
        The fifth step is to investigate sources for answers. This involves searching for and accessing relevant data and information that will help you answer your research question.
        
        Step 6: Collect Data as per Protocol
        The sixth step is to collect data as per protocol. This involves implementing the methods outlined in your protocol and collecting the data specified. You should ensure that your data collection methods are rigorous and reliable.
        
        Step 7: Data Extraction
        The seventh step is to extract the data. This involves organizing and analyzing the data you have collected, and extracting the relevant information that will help you answer your research question.
        
        Step 8: Critical Analysis of Results
        The eighth step is to conduct a critical analysis of your results. This involves interpreting your findings, identifying patterns and trends, and drawing conclusions based on your data.
        
        Step 9: Interpreting Derivations
        The ninth step is to interpret the derivations. This involves taking the conclusions you have drawn from your data and interpreting them in the context of your research question.
        
        Step 10: Concluding Statements
        The final step is to make concluding statements. This involves summarizing your findings and drawing conclusions based on your research. You should also provide recommendations for future research and implications for practice.
        
        Step-11:
        Please include references in the form of citation and also link to the reference papers.

        ### Getting Started:
        1. Enter your OpenAI API key in the field below and click "Set API Key"
        2. Upload multiple PDF research papers (2 or more recommended)
        3. Enter your review question or topic
        4. Check the "Include Tables" option if you want the review to include comparison tables
        5. Click "Generate Systematic Review" to start the process
        
        ### Tips:
        - For best results, upload papers that are related to the same research topic or field
        - Be specific in your review question to get more focused results
        - The generated review will follow a systematic structure including research field identification, data extraction, analysis, and conclusions
        - The more papers you upload, the more comprehensive the review will be
