Does Hand Washing among Healthcare Workers Reduce Hospital Acquired Infections?

On the paper I uploaded I need weeks 3 and 4 on the paper matrix that I uploaded filled out with 5 primary research articles. Here are the paper guidelines * The objective of this assignment is to develop a written matrix using your five discovered PRIMARY research articles relevant to your selected topic. The ultimate goal of developing this matrix is to assist you in summarizing and synthesizing your research findings. The summary boxes you develop at the end of each section will be used as the foundation for your literature review portion of your final research paper. Each article will not contain ALL fields requested; however you should complete the matrix to the best of your ability using the information presented in your articles.
