Table 5 Baseline and Month 12 CAJIS Scores of the NHS Cohort, by ECG category. Mean CAJIS scores of baseline data and 12 month follow up data based on ECG classification. * represent significant differences from CAJIS scores of the Normal ECG subgroup (p < 0.05). Scores were obtained by assigning each joint/region as: 0 = uninvolved; 1 = partially involved; 2 = completely ankylosed. Total (cumulative) scores ranged from 0 to 30, with higher scores indicating more severe limitations in mobility and function
