Predictors of Calcinosis Odds Ratio (95% CI) P value
Gottron’s papules (ever) a 0.005
Disease duration (per year) 1.12 (1.03-1.21) 0.006
Constipation (ever) b 0.006
Periungual capillary changes (ever) 8.65 (1.63-46.08) 0.007
Age at diagnosis (per year) 0.81 (0.70-0.95) 0.008
Falling episodes (ever)c 5.89 (1.38-25.23) 0.01
Clinical subgroup (JDM, JPM, JCTM) c 0.01
Lipodystrophy (ever) 5.07 (1.21-21.28) 0.02
Contractures (ever) 3.98 (1.02-15.51) 0.04
a

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.

b

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.

c

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.
