photoelectric effect ejection of electrons from matter as a result of interaction with photons from high frequency electromagnetic radiation, such as x-rays; the ejected electrons may be energetic enough to ionize multiple additional atoms.
placebo effect the total of all nonspecific effects, both good and adverse, of treatment; it refers primarily to psychological and psychophysiological effects associated with the caregiver-patient relationship and the patient's expectations and apprehensions concerning the treatment. See also placebo.

pressure effect the sum of the changes that are due to obstruction of tissue drainage by pressure.
proarrhythmic effect any new, more advanced form of arrhythmia caused by an antiarrhythmic agent, especially those that produce hemodynamically important symptoms.

side effect a consequence other than that for which an agent is used, especially an adverse effect on another organ system.

effect

a result produced by an action. The relationship between the two can be expressed in linear form. The total association between them may be the sum of a number of effects. The effect may be direct when it is exerted without being transmitted through intervening factors, or indirect when it is. It may also be a spurious effect when the observed changes are due to causes and correlations common to both.

additive effect

cumulative effect

effect modifier
a factor which modifies the effect of a causal factor under study. Called also interaction.
position effect
in genetics, the changed effect produced by alteration of the relative positions of various genes on the chromosomes.
pressure effect
the sum of the changes that are due to obstruction of tissue drainage by pressure.
side effect
a consequence other than that for which an agent is used, especially an adverse effect on another organ system.
