I have completed an initial data-extraction run for a meta-analysis that covers 20 published studies and 14 predefined questions per study. Before I proceed to analysis, I want a medically trained eye to double-check every field. The task is purely verification and double re extraction if required. full articles are available . Scope • Quantitative material sits in structured database entries (one record per study, 20 variables per record). • Qualitative answers are stored in accompanying text documents. • Both sets must be cross-checked against the original articles to confirm accuracy, completeness, and consistency. What you’ll do 1. Open the database, review each numeric and coded field against its source, and flag or correct any mismatch. 2. Read the linked text documents, ensure the qualitative answers accurately reflect the corresponding study content, and standardise wording where needed. 3. Keep a concise change log explaining every correction or doubtful item so I can trace decisions easily. Deliverables • Updated database file with all verified quantitative fields. • Revised text documents or an annotated copy showing edits. • A change log (spreadsheet or doc) summarising discrepancies, corrections, and any unresolved queries. Acceptance criteria ✓ Every one of the 200 data points (14 questions × 20 studies) is either confirmed or corrected. ✓ All corrections are referenced to page, table, or paragraph of the source paper. ✓ No outstanding uncertainties remain without a clear comment. Familiarity with clinical research reporting standards and quick access to full-text articles will help you fly through this. Let me know your expected turnaround and any clarifying questions.

Hello, I have 20+ years of quantitative and qualitative research experience, including academic studies, data validation, SPSS/Excel analysis, and publication-ready reporting. I can verify every numeric, coded, and qualitative entry against the original articles, correct inconsistencies, add exact page/table/paragraph references, standardise wording, and maintain a clear change log. I would use a two-pass review: field-by-field verification followed by cross-study consistency checks. The main problem I believe in qualitative entry data, so I before we start I want to know how big the qualitative answers are and what exactly is required to do. If work take about 5-6 hours I can take to do it. If more then rediscuss the budget.

Meta-analysis verification requires systematic cross-referencing of 280 data points against source materials—a task where precision errors compound quickly across statistical datasets. This project aligns directly with core competencies: medical research data validation, SPSS database management, qualitative research documentation, and statistical accuracy verification. The scope demands clinical research literacy to catch discrepancies between extracted fields and original articles, then produce auditable change logs that defend every correction. Deliverables match existing expertise: database verification against source materials, qualitative text standardization, and detailed change documentation with source attribution (page/table references). Familiarity with research reporting standards ensures corrections follow clinical conventions, not assumptions. Turnaround depends on article complexity and database structure. With full-text access provided, expect 7-10 business days for 20 studies with comprehensive verification and annotated change log. Ready to start immediately upon receiving database file and article links. Any specific data extraction standards or institutional guidelines to follow?
