Table 3 skinDAS, CAT & CDASI Mean Absolute Error (MAE) over all N observations (478)

From: Currently recommended skin scores correlate highly in the assessment of patients with Juvenile Dermatomyositis (JDM)

Measurement Tool

Standardized Mean Absolute Error (95% CI)

Skin Disease Activity Score (skinDAS)

0.89 (0.81–0.97)

Cutaneous Assessment Tool (CAT)

0.93 (0.85—1.01)

Cutaneous Dermatomyositis Disease Area and Severity Index (CDASI)

1.02 (0.94—1.10)

  1. Standardized MAE values were calculated for each measurement tool by taking the sum of the absolute value of the differences between the GEE model’s predictions of the global Physician VAS and the observed values and dividing them by the total amount of observations (478 observed values), 95% confidence intervals are included
