Skin Thickness Alterations in Pressure Injury Tissue from High-Frequency Ultrasound

Skin thickness measurements from 42 bedridden patients with pressure injuries, comparing injury sites to adjacent normal sites using high-frequency ultrasound (18 MHz). The data was collected by Lin Tang in a prospective comparative study and published on figshare under a CC-BY-4.0 license. The dataset includes results from a mixed-design ANOVA analyzing the effects of tissue type, pressure injury risk status, and body mass index.

Use Cases

• Validate high-frequency ultrasound as a tool for pressure injury detection based on skin thickness measurements.
• Model the relationship between systemic risk factors (e.g., high-risk status) and local tissue pathology.
• Benchmark skin thickness changes in pressure injury tissue against adjacent normal skin.
• Investigate potential interaction effects between tissue type and patient risk factors.

Strengths

• Includes measurements from 42 patients, providing a basis for statistical analysis.
• Uses a validated statistical method (mixed-design ANOVA) with reported effect sizes (generalized eta-squared).
• Compares paired measurements (injury site vs. normal site) within the same patient, controlling for individual variation.

Limitations

• Row count is unknown, which may limit suitability assessment.
• Column-level documentation is absent; field semantics must be inferred after download.
• Dataset is small (151.5 KB), indicating limited scope.
