Confounders can make it difficult to determine the true relationship between the exposure and the outcome, because they can create the semblance of a more direct association that is not actually present.

Adjusted measures of association can give a more accurate estimate of the true relationship between the exposure and the outcome, because they take into account the effect of confounders by statistically controlling for them.
