Methodology appropriateness and completeness
Criteria Feedback
- Topic is communicated accurately and effectively with comprehensive explanations of ultraprocessed foods, maternal nutrition, and cognitive development.
- Research question is clearly stated, focused, and maintained throughout the investigation.
- Methodology is justified with a clear rationale for study selection and statistical test choice.
- Occasional digressions into historical anecdotes reduce conciseness.
- Some sections (e.g., maternal diet) lack direct linkage back to the research question.
- Limited discussion of exclusion criteria and statistical assumptions (e.g., normality) in methodology.

Use of terminology and concepts
Criteria Feedback
- Terminology (e.g., β-coefficients, p-values, neural differentiation) is used accurately and consistently.
- Source material is applied effectively, with primary data re-analysed and integrated into tables.
- Technical details (e.g., list of additives, placenta nutrient exchange) are presented with coherence.
- Much narrative remains descriptive, with limited synthesis across different studies.
- A few mechanistic links (e.g., oxidative stress pathway) lack specific citations.
- Stylistic inconsistencies (capitalization, symbol formatting) occasionally interrupt flow.

Argument development
Criteria Feedback
- Analysis is sound: t-tests are correctly performed and results tied explicitly to the research question.
- Evaluation identifies key strengths and weaknesses (e.g., sample size, bias, confounders).
- Argument is coherent and well structured from introduction through to conclusion.
- Statistical assumptions (normality, variance homogeneity) are not checked or discussed.
- No meta-analytic weighting or confidence interval recalculation to deepen quantitative evaluation.
- Discussion of practical significance (effect sizes) and mitigation strategies for biases is limited.

Layout and formatting
Criteria Feedback
- The report follows the required structure (title page, contents, main sections) with labelled tables and figures.
- Word count, title, and page numbers are correctly presented.
- Layout is generally neat and navigable.
- Abstract and appendices are missing, reducing overall completeness.
- Formatting inconsistencies (OCR artifacts in footnotes, misaligned table borders) distract the reader.
- Some figures (e.g., fetal development diagram) are not referenced inline, affecting flow.
