Risk curve

Used to demonstrate inadequacy or excess of a particular nutrient. As defined in the usual statistical sense, a risk curve is in contrast to the concept of probability curve.

Risk of excess

In relation to the DRIs, the likelihood that an individual will exceed the UL for a particular nutrient.

Risk of exposure

In the toxicological sense, the likelihood that individuals will experience contact with a toxin (or consume levels of a nutrient above the UL).

Risk of inadequacy

The likelihood that an individual will have usual intake of a particular nutrient that is less than the individual's requirement.

Sensitivity analysis

Technique of varying the implicit assumptions or presumed conditions of an analysis approach to see how much this affects the overall outcome.

Skewed distribution

A distribution that is not symmetrical around its mean. For example, a skewed distribution can have a long tail to the right (right-skewed distribution) or to the left (left-skewed distribution).

Symmetrical distribution

A distribution that has the same number of values (observations) above and below the mean and has equal proportions of these values around the mean.

Threshold

The point in a dose-response curve that is accepted as the point beyond which a risk of adverse effects occurs.

Toxicity

An adverse condition relating to or caused by a toxin.
