imap: Data from the IMAP study
In kaneplusplus/preference: 2-Stage Preference Trial Design and Analysis
Description
The “Improving Management of Abnormal Pap Smears” study used a
two-stage randomized preference trial design to evaluate psychosocial
outcomes in women found to have atypical cells in a Pap Smear.
Two systems for managing the atypical cells were tested (repeated Pap smears
or HCV triage) and a doubly randomized design was used to evaluate the role
of patient preference. The data set provides mean, standard deviation and
sample sizes of the SF36 outcome for each treatment in both the choice and
random arms.
Three data sets are provided with the preference package based on the
IMAP study. The first, imap_summary provides summary statistics
of the entire trial. The second imap_summary_stratified, summary
statistics of the study per strata. The third imap is a resampled
version of the individual level data including stratification. Each
of these data sets are compatible with the analysis functions
fit_preference_summary, fit_preference, and
preference, provided in this package. The examples sections
in the documentation illustrate their use.
