ASSIST Trial Data from Yudkin and Moher 2001
Description
The ASSIST Trial baseline data from Yudkin and Moher 2001 consist of 21
general practices containing 2142 patients used for the design of a
randomized trial which assigned to three treatments aiming to compare methods
of preventing coronary heart disease. This data frame is aggregated
to the practice level. We added a simulated randomized treatment variable.
Usage
ym_short
Format
A data frame with 21 rows and 8 columns
practice: Identifier for the practice
n_practice: Number of patients with CHD in the practice
assessed: Whether a patient was coded as "adequately assessed" (the
outcome of the study, measured here at baseline).
aspirin: Whether a patient was treated with aspirin at baseline.
hypo: Whether a patient was treated with hypotensives at
baseline.
lipid: Whether patient was treated with lipid-lowering drugs
at baseline.
assess_strata: Strata of the practice defined by the proportion of
people adequately assessed at baseline (three strata, following Yudkin
and Moher 2001).
trt: A simulated binary treatment, assigned at random at the practice
level within levels of assess_strata.

The data come from Table II on page 345 of Yudkin and Moher 2001,
