Values below the limit of detection (1∶10 titer) were assigned a value of one-half the lowest dilution tested (i.e., a value of 5) when calculating geometric mean titer.

For the purpose of calculations, negative titers reported as <10 were assigned a value of 5, while high titers reported as greater than or equal to a given value were assigned a value corresponding to the next 2-fold titer; e.g., the value of ≥1,280 was assigned a value of 2,560.
