Study design a/w:
identifies diseased group and healthy group and retrospectively compares them

Back 4

case control

Front 5

Study design a/w:
weakened by recall and selection bias

Back 5

case control

Front 6

Study design a/w:
seeks to estimate disease prevalence and exposure across the population

Back 6

cross sectional

Front 7

Study design a/w:
examines a collection of studies on a given subject

Back 7

meta analysis

Front 8

Study design a/w:
prospective blinded study involving placebos, existing therapies and expiramental interventions

Back 8

random clinical trial

Front 9

Study design a/w:
focuses on one group with a shared exposure or disease and either prospectively or retrospectively compares them

Back 9

cohort

Front 10

Study design a/w:
examines a collection of cases and seeks insight into the disease of interest

Back 10

case series

Front 12

Bias a/w:
memory errors produce incorrect data

Back 12

recall

Front 13

Bias a/w:
subject awareness of being studied alters their answers and behaviors

Back 13

observer

Front 14

Bias a/w:
certain medical studies attract subject with a particular medical history rather than general population

Back 14

self selection

Front 15

Bias a/w:
studies that show a difference are preferably published and then later included in a meta analysis rather than studies that support the null hypothesis

Back 15

publish

Front 16

Bias a/w:
screening tests designed ti detect asymptomatic disease may miss rapidly progressive disease because the interval between successive screenings only detect slowly progressing ones

Back 16

length

Front 17

Bias a/w:
screening test may allow earlier diagnosis of the disease but does not translate into actual length of survival
