Demographic and Clinical Features of 57 Dermatomyositis Patients

57 adult and juvenile dermatomyositis patients are described in this dataset, which includes demographic and clinical features. The data was authored by Meghan Corrigan Nelson and last updated in March 2026. It contains 709 measurements gathered from 443 calcinosis lesions and 266 control lesions across eleven anatomic regions.

Use Cases

• Analyze the correlation between qualitative physician assessments and handheld digital durometer measurements for 443 calcinosis lesions.
• Compare clinical features like calcinosis lesions across adult and juvenile patient cohorts within the 57 enrolled patients.
• Assess rater reliability by examining intraclass correlations for measurements taken across eleven anatomic regions.
• Investigate the distribution of 709 durometer measurements between calcinosis lesions and 266 control lesions on healthy unaffected skin.

Strengths

• Contains data from 57 enrolled patients, providing a focused clinical cohort.
• Includes 709 specific measurements gathered using a handheld digital durometer.
• Covers eleven anatomic regions, allowing for detailed anatomic analysis of lesions.
• Explicitly documents 443 calcinosis lesions and 266 control lesions for comparison.

Limitations

• The dataset is very small at 9.5 KB, limiting statistical power for complex analyses.
• The patient sample size of 57 may not be representative of the broader dermatomyositis population.
• Specific column names and data structure are unknown, requiring inspection of the XLS file.
