Completed a stem-to-stern copyedit. Reordered some introductory text to avoid duplication and make the text flow better. Some rephrasing to reduce medical jargon and make the article more generally accessible in keeping with the Manual of Style for medicine-related articles. Updated journal references to use the cite journal template. Moved bare links to references where possible; removed some links that are now broken, replacing them where possible.
