Twenty peer-reviewed health-related papers (PDFs and citation files) are ready for a close examination. I need each article reviewed with three lenses in mind: pinpointing any methodological or interpretive bias, capturing the core findings in plain language, and flagging clear gaps that future studies could address. Workflow • Read and annotate every paper. • For each one, complete a concise summary (≈150 words), a bias assessment (study design, sampling, analysis, funding/conflict of interest), and a short list of unanswered questions. • Compile the results into a comparative matrix (Excel or Google Sheet) followed by a two-page narrative synthesis that weaves the patterns together. Deliverables 1. Annotated PDFs (highlights & margin notes). 2. Summary / bias / gap matrix. 3. Narrative synthesis (doc or Google Doc). Acceptance criteria • All 20 papers covered; no section left blank. • Bias observations supported with direct page or figure references. • Narrative clearly distinguishes consensus, contradiction, and missing evidence. When you submit your bid, include a brief but detailed project proposal outlining your approach, any systematic-review tools you prefer (e.g., Rayyan, Zotero, NVivo), and the expected turnaround time.
