Using only the papers in this notebook, build a literature review matrix on {{review_topic}} to support {{project_or_thesis}}. Keep this guiding question in focus: {{guiding_question}}. Treat each paper as a separate source and cite it for every entry. If a paper does not report something, write not reported rather than inferring it, and do not bring in studies or facts from outside the notebook. The papers may be in more than one language; write the matrix in {{output_language}} and keep key terms in their original language next to the translation. Return: 1. A matrix with one row per paper: authors and year, aim, design and method, sample and setting, key findings, limitations, relevance to my question 2. Where the papers agree, with citations 3. Where they conflict, and likely reasons such as different samples, methods, or definitions 4. Gaps that no paper addresses 5. Themes to organize a written review around 6. The papers to read in full first, and why
