Log antibody response
The difference in the logarithm of the antibody titer between two points in time or two conditions expressed as the result of the subtraction in and of itself without comparison by ratio with another quantity. A logarithm is the power to which a base, such as 10, must be raised to produce a given number.
The term "absolute change" refers to the subtraction of one value from another, as opposed to a dissimilarity of two values expressed as a ratio or as a percentage. In this context it is not intended to necessarily imply the difference expressed as an absolute value |n|, that is, the numeric value of the difference without regard to its sign.
