Systematic Review and Meta-Analysis of Nutrition Education for Dialysis Patients

44 studies with 4,106 participants were analyzed to quantify the effect of nutrition education on dialysis patients. The review, published on figshare in 2026, found significant improvements in patient knowledge and quality of life, with modest reductions in serum potassium and phosphate. Most outcomes were graded as low or very low certainty, indicating a need for higher-quality trials.

Use Cases

• Evaluating the effectiveness of patient education programs based on reported clinical outcomes like serum potassium and phosphate.
• Conducting meta-regression analyses based on study characteristics and intervention types described in the review.
• Assessing publication bias in clinical nutrition research based on the application of Egger and Begg tests.
• Informing clinical practice guidelines based on the GRADE certainty assessments for different health outcomes.

Strengths

• Includes data from 44 studies comprising 4,106 participants, providing a substantial evidence base.
• Employs a rigorous methodology including risk-of-bias assessment (RoB-2, ROBINS-I) and GRADE certainty grading.
• Reports specific effect sizes, such as a standardized mean difference (SMD) of 1.43 for health-related quality of life.

Limitations

• Column-level documentation is absent; field semantics must be inferred after download.
• The underlying data's structure and granularity are not described, limiting suitability assessment.
• The review notes that most outcomes were rated low or very low certainty due to inconsistency and imprecision.
