cohort study
Framingham heart study is an exampel of this type of study
cohort study

this negative study finding occurs when 1 outcome is systematically favored over another.
this type of bias is a nonrandom assignment to a study group
selection bias
this type of bias occurs when knowledge of the presence of a disorder alters recall by the subjects
recall bias
this type of bias occurs when subjects are not representitive; tehrefore results are not generalizable
sampling bias
this type of bias occurs when information is gathered at an inappropriate time
late-look bias
Give 4 ways to reduce bias:
1) blind studies (single/double)

this describes total cases in population at a given time over total population
this describes new cases in population over a given time over total population at risk during that time

mneu: incidence is new incidents.

note: when calculating incidence, don't forget that people previously positive for dz are no longer considered at risk
this is approximately equal to the incidence multiplied by the dz duration
what is greater for chronic dzs like diabetes. prevalence or incidence
which is greater for acute dzs like the common cold. prevalence or incidence
they are equal
this describes the number of true positives divided by the number of all the people with the dz. It is the probability a positive test, given a person has the desease
sensitivity rules ______

mneu: SNOUT
this is equal to 1-sensitivity
false negative
high sensitivity is desirable for this type of test
This is the number of true negatives divided by number of all people without the desease. It is the probability of a negative test given taht a person is free of the dz.
specificity rules _____

mneu: SPIN
this is equal to 1-specificity
false positive rate
high specificity is desirable for this type of test
confirmatory test
This is the number of true positives divided by number of people who tested positive for the dz.

It is the probability of having a condition given a positive test
positive predictive value (PPV)
This is the number of true negatives divided by number of people who tested negative for the dz.

It is the probability of not having the condition given a negative test
negative predictive value (NPV)
unlike sensitivity and specificity, predictive values are dependent on this
prevalence of the dz

the higher the prevalence off the diz the higher the positive predictive value of the test.

this descrives the odds of having a dz in the exposed gorup divided by the odds of having dz in unexposed group.
odds ratio (OR)
how are odds are calculated within a group
as number with dz divided by number without the dz

graphic odds ratio v. relative risk p. 63
the consistency and reproducibility of a test (reliability)

the absense of random variation in a test
the trueness of test measurements (validity)

this describes a hypothesis of no difference. E.g., there is no association between the dz and risk factor in the population

this describes a hypothesis that there is some difference (e.g., there is some association between the dz and the risk factor in the population
Alternative hypothesis (H1)
image - statistical hypothesis p. 64
This type of error is stating that there IS an effect or difference when none exists (to mistakenly accept the experimental hypothesis and reject the null hypothesis).
Type I error (α)
ρ is judged against α, a preset level of significance (usually <0.5). ρ=
probability of making a type I error
if ρ < .05 then
there is less than a 5% chance that the data will show something that is not really there
you saw a difference that idd not exist--for example, convicting an innocent man
This type of error states that there IS NOT an effect or difference when one exists (to fail to reject the null hypothesis when in fact Ho is false.
type II error (β)
the probably of making a type II error

you did not "see" a difference that does exist--for example, setting a guilty man free
This is the probability of rejecting a null hypothesis when it is in fact false.
power (1-β)
Power depends on:
1) total number of end points experienced by population
2) difference in compliance b/n tx groups (differences in the mean values between groups)
3) size of expected effect
