Figure 2: N1 Ct values of common clades in saliva.

Figure 2:

We analyzed the Ct values from a total of 1297 SARS-CoV-2 positive saliva samples, using the N gene target. 2A: Comparison of all samples. Delta (n=787) showed a statistically significant difference in Ct value when compared to 20G (n=159), Alpha (n=258), and Gamma (n=87). 2B: Comparison of surveillance samples. When only surveillance samples were considered, the same trends were observed, showing a significant difference between Delta (n=691) and all other clades (20G: n=95, Alpha: n=181, Gamma: n=86). Both groups also showed a significant difference when comparing Alpha and 20G. 2C. Comparison of symptomatic samples. There were no significant differences in Ct values observed among symptomatic samples for Delta (n=70), Alpha (n=58), Gamma (n=1), and 20G (n = 39). *p.adj<0.05, **p.adj<0.01, ***p.adj<0.001, ****p.adj<0.0001.
