Calcinosis Lesion Characteristics and Durometry Measurements in Dermatomyositis

Figshare hosts a dataset on calcinosis lesions in patients with dermatomyositis (DM) and juvenile dermatomyositis (JDM). It contains data from 57 enrolled patients, covering 443 calcinosis lesions and 266 control sites across eleven anatomic regions. The data includes durometry measurements and qualitative physician assessments gathered at the initial patient visit.

Use Cases

• Analyze the correlation between durometry measurements and qualitative physician assessments of calcinosis lesions.
• Compare characteristics of 443 calcinosis lesions against 266 control sites across eleven anatomic regions.
• Assess rater reliability for durometry measurements and lesion assessments in DM and JDM patient cohorts.
• Model lesion characteristics to understand factors contributing to significant morbidity in dermatomyositis.

Strengths

• Data is derived from a study of 57 enrolled patients, providing a focused clinical cohort.
• Includes measurements for 443 specific calcinosis lesions and 266 control sites for comparison.
• Covers assessments across eleven anatomic regions, allowing for anatomic-specific analysis.
• Combines quantitative durometry measurements with qualitative physician assessments.

Limitations

• The dataset is very small at 5.5 KB, indicating limited scope and likely a small number of data points.
• Data is limited to the initial patient visit only, providing no longitudinal or follow-up information.
• Potential for rater variability in measurements and assessments, as indicated by the 'Rater Reliability Varied' tag.
