Simulation study results are summarized.
psborrow.summary(object)The psborrow.summary returns a list containing the following objects:
Data frame containing (1) rate that the null hypothesis is
rejected in Bayesian one-sided hypothesis testing, (2) bias in posterior mean
of treatment effect (log hazard ratio, log odds ratio, or mean difference),
(3) empirical standard deviation (EmpSD), derived by taking the
standard deviation of posterior mean of treatment effect that each simulated
trial yielded, (4) model standard deviation ((ModSD)), derived by
taking the average of posterior standard deviation of treatment effect that
each simulated trial yielded, (5) ratio of ModSD to EmpSD,
(6) Coverage probability of credible interval.
Data frame containing (1) mean, median, and standard deviation of overlapping coefficients of propensity score densities between treatment versus concurrent control plus external control and between concurrent control versus external control, (2) mean, median, and standard deviation of overlapping coefficients of continuous covariate densities between treatment versus concurrent control plus external control and between concurrent control versus external control, and (3) mean, median, and standard deviation of rate differences of binary covariate between treatment versus concurrent control plus external control and between concurrent control versus external control.
Number of patients in treatment group in the current trial.
Number of patients in concurrent control group in the current trial.
Number of patients in external control pool.
Number of patients in external control.
Hazard ratio, odds ratio, or mean difference between concurrent and external control for which the bias should be plotted. The measure depends on the outcome type.
Method of estimating the propensity score.
Link function used in estimating the propensity score.
Options of who to match.
Matching method.
Order that the matching takes place when a nearest neighbor matching is used.
