Tibialis Anterior Pennation Angle and 60-Day Mortality in 247 Critically Ill Patients

A 2024 prospective observational study of 247 critically ill adult patients from two centers. The dataset, authored by Yu Zhou, includes ultrasound-derived muscle indices measured within 24 hours of ICU admission and their association with 60-day all-cause mortality.

Use Cases

• Predicting 60-day mortality in ICU patients based on ultrasound muscle quality indices mentioned in the description.
• Building a risk stratification nomogram using the tibialis anterior pennation angle, APACHE II score, and prealbumin level.
• Comparing the predictive power of muscle quantity (e.g., rectus femoris thickness) versus quality (pennation angle) for clinical outcomes.
• Validating clinical prediction models through internal validation methods like decision curve analysis described in the study.

Strengths

• Includes data from 247 patients with a median age of 61.0 years.
• Prospective design with measurements taken within a standardized 24-hour window of ICU admission.
• Model performance is quantified with a C-index of 0.785 and validated via decision curve analysis.

Limitations

• Column-level documentation is absent; field semantics must be inferred after download.
• Row count is unknown, which may limit suitability assessment.
• Data is from a single-year, dual-center study and may reflect geographic or institutional bias.
