It can be used when discussing a standard or benchmark that is used for comparison in various contexts, such as scientific research or data analysis.
Example: "The study established a reference value against which all subsequent measurements could be compared."
Alternatives: "a benchmark for" or "a standard for comparison".

To some extent, the preventability of the attributable burden is also influenced by its method of estimation (in particular the counterfactual, or reference value, against which the impact of current exposure burden was estimated, or in the case of expert evaluation the formulation of the question; see sections (a) and (b) below).
