Calculate the appropriate measure of association

Reference no: EM133333179

Case Study: A case-control study was conducted among women enrolled in Medicaid to estimate the association between cocaine or methamphetamine use and the risk of stroke. The investigators attempted to identify all incident strokes (both fatal and non-fatal) in women aged 15-44 years old from 2017-2019. Stroke cases were identified from the following sources: hospital admissions, hospital discharge records, emergency department logs, and requests for out-of-plan hospitalizations. Controls were selected at random from women enrolled in Medicaid aged 15-44 years old. If a patient with stroke had died or was unable to communicate verbally, the investigators attempted to interview a proxy. Study staff conducted face-to-face interviews of both stroke patients and control subjects to obtain information on the use of cocaine and methamphetamine in the week before the clinical presentation of stroke for cases, or a corresponding date for controls. Use of cocaine/amphetamines was reported by 20 of the 347 cases and 7 of the 1021 controls.

Question: Calculate the appropriate measure of association between use of cocaine/amphetamines and the risk of stroke in this case-control study. Then tell me what is the estimated prevalence of cocaine/methamphetamine use among the population that gave rise to the cases?
