Reporting Odds Ratio (ROR)

Meaning

In the critical clinical domain of pharmacovigilance and hormonal therapy safety, the Reporting Odds Ratio (ROR) is a specific statistical measure used to detect the disproportionate reporting of a particular adverse event relative to a drug or hormonal agent within spontaneous reporting databases. It functions primarily as an initial signal detection tool, not a measure of absolute risk, that helps clinicians identify potential, unexpected safety concerns requiring further, rigorous epidemiological study.
