unadjusted odds rationsORs

Unadjusted odds ratios (ORs) are measures of association between an exposure and an outcome, without taking into account any potential confounding factors. They are calculated by dividing the odds of the outcome in the exposed group by the odds of the outcome in the unexposed group. Unadjusted ORs can provide an initial estimate of the strength of the association between the exposure and the outcome, but they may be biased if there are other factors that are related to both the exposure and the outcome. Adjusted ORs are typically used in statistical analyses to control for potential confounding factors.
