Odds ratio could not be calculated: 62.8% of patients with history of Gottron’s papules and 0.0% of those without Gottron’s papules had calcinosis at last assessment.
Odds ratio could not be calculated: 100.0%> of patients with history of constipation and 46.3%> of those without constipation had calcinosis at last assessment.
Odds ratio could not be calculated: 57.1%> of JCTM patients, 62.2% of JDM patients, and 0.0%> of JPM patients had calcinosis at last assessment.
