Supplementary Material for: Integrated Ultrasound Approach to Fluid Assessment and Nutriti

A 315.9 KB DOCX file containing supplementary material for a single-center retrospective observational cohort study of 47 adult maintenance hemodialysis patients. The study, authored by figshare admin karger and last updated on 2026-04-20, integrated lung ultrasound, modified Venous Excess Ultrasound Score, bioimpedance analysis, and nutritional ultrasound to assess fluid status and correlate it with malnutrition.

Use Cases

• Analyzing the correlation between ultrasound-based congestion criteria and malnutrition parameters like cross-sectional muscle area.
• Studying the integration of multiple non-invasive assessment tools (LUS, mVExUS, BIA, NUS) for fluid status.
• Investigating changes in congestive patient metrics, such as NT-proBNP and portal vein pulsatility, over a five-week period.

Strengths

• Provides a descriptive framework for multimodal assessment integrating four distinct measurement techniques.
• Includes specific, predefined congestion criteria combining mVExUS score, B-line burden, and ECW/TBW ratio.
• Reports statistically significant differences in cross-sectional muscle area between congestive and non-congestive groups.

Limitations

• Description metadata is limited; actual data quality requires manual inspection after download.
• Column-level documentation is absent; field semantics must be inferred after download.
• Row count is unknown, which may limit suitability assessment.
