Duration

A measure of how much longer an effect will last. This number is displayed in parentheses after the name of the effect in the left-hand pane, and decrements by one for each energy you spend. For example, an effect with duration (30) will disappear after you spend 30 energy.

Some effects can be also be removed in ways other than just waiting for them to run out - for example: taking antidotes to poison effects, replacing an injured body part with a cyberware equivalent or using Etheric techniques, and many more. See the "Removed By" section of individual effect pages for details.
