Fig. 7From: Frequency of circulating topoisomerase-I-specific CD4 T cells predicts presence and progression of interstitial lung disease in sclerodermaFrequency of topoisomerase-I-specific CD4+ T cells does not correlate with anti-topoisomerase-I antibody serum concentration. Serum anti-topoisomerase-I antibody concentration is measured in units of reactivity compared to a standard low positive sample as per manufacturer’s instructions. Pearson correlation coefficient r and p value are displayedBack to article page
