Correlation between the T/C ratios of UPT-POCT and NAb titers in 528 serum samples. The corresponding relation between -Log2(neutralizing titer) and neutralizing titer: 2 (1:4), 3 (1:8), 4 (1:16), 5 (1:32), 6 (1:64), 7 (1:128), 8 (1:256), 9 (1:512), 10 (1:1024), 11 (> 1:1024). a Linear regression analysis (n = 527). The error bar for neutralizing titer ranging from 1:4 to > 1:1024 is derived from the detection results for 16, 46, 54, 140, 75, 103, 40, 33, 14, and 6 samples, respectively. b Spearman correlation analysis (n = 528). Compared with linear regression analysis, we included a sample with a neutralizing titer of 1:4 and a T/C ratio of 38.54
