Subject field(s)
  • Epidemiology
DEF

The ratio (quotient) of the exposure odds among the cases (subjects who are ill or have died, for example) to that among the controls (subjects who are not ill or who are alive, for example).

OBS

The odds ratio is the estimate of relative risk used in a type of study (case-control) in which it is impossible to calculate relative risk directly. It is a good estimate of relative risk in cases in which the disease is rare. Thus, if the results of a trial are that the probability of death is 25% in the control group and 10% in the experimental group, the odds ratio of survival is 0.10 ÷ (1.0 - 0.10) ÷ (0.25 ÷ (1.0 - 0.25) = 0.33.

Domaine(s)
  • Épidémiologie
DEF

Rapport (quotient) entre la cote d’exposition chez les cas (sujets malades ou décédés, par exemple) et chez les témoins (sujets non malades ou vivants, par exemple).

OBS

Le rapport des cotes est l’estimation du risque relatif utilisée dans un type d’étude (cas/témoins) où il est impossible de calculer directement le risque relatif. C’est une bonne estimation du risque relatif dans les cas où la maladie est rare. Ainsi, si les résultats d’un essai sont que la probabilité de décès dans le groupe témoin est de 25 % et que la probabilité de décès dans le groupe expérimental est de 10 %, le rapport des cotes de survie serait 0,10 ÷ (1,0 - 0,10) ÷ (0,25 ÷ (1,0 - 0,25) = 0,33.
