Figure 5. Inter-scores correlations in SLE patients.

Figure 5

A: Modular IFN score (absent/mild/moderate/strong) is compared to 4 scores from the literature using the 157 SLE samples of the present cohort. Linear model shows an increase in the Yao score of 2.9 points per category of modular IFN score (p<0.0001), an increase in the Petri score of 1.85 points per category (p<0.0001) and an increase in the Feng score of 9.14 points per category (p<0.0001). Both IFN-α and IFN-γ Kirou’s scores were linked (chi-squared test for trend in proportions p<0.0001) with modular IFN score. B: Petri IFN score in 29 patients with ≥ 3 visits (longitudinal cohort) across time. A limited inter-individual variability of the Petri IFN score across time is observed (coefficient of variability = 0.07). This score is based on the expression of 3 IFN-inducible genes (IFI27, IFI44 and OAS3).
