  2. Attributable fraction for the population - Wikipedia

    en.wikipedia.org/wiki/Attributable_fraction_for...

    Attributable fraction for the population combines both the relative risk of an incident with respect to the factor, as well as the prevalence of the factor in the population. Values of AF p close to 1 indicate that both the relative risk is high, and that the risk factor is prevalent.

  3. Risk difference - Wikipedia

    en.wikipedia.org/wiki/Risk_difference

    The adverse outcome (black) risk difference between the group exposed to the treatment (left) and the group unexposed to the treatment (right) is −0.25 (RD = −0.25, ARR = 0.25).

  4. Attributable fraction among the exposed - Wikipedia

    en.wikipedia.org/wiki/Attributable_fraction...

    In epidemiology, attributable fraction among the exposed (AF e) is the proportion of incidents in the exposed group that are attributable to the risk factor. The term attributable risk percent among the exposed is used if the fraction is expressed as a percentage. [ 1 ]

  5. Population impact measure - Wikipedia

    en.wikipedia.org/wiki/Population_impact_measure

    N is the number of people in the population; I p is the baseline risk of the outcome of interest in the population as a whole; t is the amount of time over which the outcome is measured. The PAR or PAF, population attributable risk (or fraction), is calculated for two or multiple strata. The basic formula to compute the PAR for dichotomous ...

  6. Preventable fraction for the population - Wikipedia

    en.wikipedia.org/wiki/Preventable_fraction_for...

    It is calculated as = /, where is the incidence in the exposed group, is the incidence in the population. [ 1 ] [ 2 ] It is used when an exposure reduces the risk, as opposed to increasing it, in which case its symmetrical notion is attributable fraction for the population .

  7. Infection rate - Wikipedia

    en.wikipedia.org/wiki/Infection_rate

    The number of infections equals the cases identified in the study or observed. An example would be HIV infection during a specific time period in the defined population. The population at risk are the cases appearing in the population during the same time period. An example would be all the people in a city during a specific time period.

  8. Compartmental models in epidemiology - Wikipedia

    en.wikipedia.org/wiki/Compartmental_models_in...

    For the full specification of the model, the arrows should be labeled with the transition rates between compartments. Between S and I, the transition rate is assumed to be (/) / = /, where is the total population, is the average number of contacts per person per time, multiplied by the probability of disease transmission in a contact between a susceptible and an infectious subject, and / is ...

  9. Basic reproduction number - Wikipedia

    en.wikipedia.org/wiki/Basic_reproduction_number

    is the average number of people infected from one other person. For example, Ebola has an of two, so on average, a person who has Ebola will pass it on to two other people.. In epidemiology, the basic reproduction number, or basic reproductive number (sometimes called basic reproduction ratio or basic reproductive rate), denoted (pronounced R nought or R zero), [1] of an infection is the ...
