Prevalence of FLEDR and TRAELDT in patients with SSc divided by clinical subtypes.

aadjusted standardized residual >1.96 indicates that the number of cases in that cell is significantly larger than would be expected if the null hypothesis were true (represented in bold), with a significance level of.05. An adjusted residual bwhen comparing different subgroups for FLEDR association: DcSSc/LcSSc/healthy controls: χ2 = 29.1, p−5; LcSSc/healthy controls: not significant; DcSSc/healthy controls: χ2 = 28.4, p−6.cwhen comparing different subgroups for TRAELDT association: DcSSc/LcSSc/healthy controls: χ2 = 10.2, p = 0.029; LcSSc/healthy controls: not significant; DcSSc/healthy controls: χ2 = 7.2, p = 0.027.
