Figure 1.
A, Boxplots of electrochemiluminescence (ECL)–zinc transporter 8 autoantibody (ZnT8A) in 2282 normal controls and 302 new-onset type 1 diabetes (T1D) patients. With a cutoff value of index 0.010 set at the 99.8th percentile of 2282 control samples, the positivity of new-onset T1D patients was 62.3% (188/302). B, ECL-ZnT8A and radiobinding assay (RBA)-ZnT8A were compared in levels among 302 new-onset T1D patients and 2 assays were well correlated (r = 0.779; P < .001). The dotted lines represented the cutoffs for 2 assays, respectively.
