Fig 2. Bland Altman (BA) plot showing the relationship between Ct values of pooled versus individual samples.

Fig 2

BA plot was drawn to visualize the relationship between the individual Ct values of sample(s) in a pool with the mean Ct value of the positive sample(s) in the pool. BA lines (dashed lines) assign the mathematical expression of this discrepancy by obtaining the 95% CI of deviation from point estimate (0.42).
