Calcinosis Lesion Measurements for Dermatomyositis Patients

709 measurements of calcinosis and control lesions from 57 patients with dermatomyositis or juvenile dermatomyositis. The data includes assessments across eleven anatomic regions using a handheld digital durometer and qualitative physician evaluations. It contains 443 calcinosis lesions and 266 control lesions for analyzing rater reliability.

Use Cases

• Calculate intraclass correlations for rater reliability using the 709 gathered measurements across lesion types.
• Compare durometer measurements from the handheld digital durometer against qualitative physician assessments for the 443 calcinosis lesions.
• Analyze lesion measurement variability across the eleven anatomic regions documented in the dataset.
• Assess the correlation between measurements from calcinosis lesions and the 266 control lesions from healthy unaffected skin.

Strengths

• Includes 709 specific measurements gathered from patient assessments.
• Covers 443 calcinosis lesions and 266 control lesions, providing a basis for comparative analysis.
• Data is collected across eleven anatomic regions, allowing for location-specific study.
• Uses both a handheld digital durometer and qualitative physician assessments, offering multiple measurement types.

Limitations

• The dataset is very small at 9.5 KB, indicating a limited scope and sample size.
• Limited to 57 patients, which may restrict the generalizability of statistical findings.
• The specific columns and data structure are unknown, complicating immediate analysis.
