I need a full, publish-ready systematic review and meta-analysis (≈6,000 words) on essential fatty acid deficiency in children with intestinal failure, drilled down specifically to nutritional impacts. My manuscript must follow PRISMA, with a rigorous search strategy across at least PubMed, Embase, Scopus and Cochrane. Please include clinical trials, observational studies and case reports—the breadth of evidence is important for this niche topic. All extracted data have to be analysed quantitatively where possible; a random-effects model, forest plots, heterogeneity tests and sensitivity analyses are expected. Where pooling is impossible, provide a structured narrative synthesis. Referencing must be Vancouver style, fully formatted and checked in EndNote or equivalent. The text must be entirely original, verifiable through Turnitin, and written without AI assistance—I will require the similarity report. Alongside the article, prepare a conference-ready poster (A0 or 48″×36″ PDF). The poster should distil the key findings, display clear visual data representations, and include graphs and charts that mirror the forest plots and summary statistics from the paper. Deliverables: • 6,000-word Word document (PRISMA abstract, main text, tables, figures, Vancouver references) • High-resolution figures as separate PNG/SVG files • PRISMA flow diagram in editable format • RevMan or R script/output for transparency of the meta-analysis • Print-quality poster PDF with the required visuals Poster with table and graphics I will review the draft, request revisions if necessary, and release final acceptance when the work meets journal standards, reference accuracy and zero-plagiarism criteria.
