R is a free software environment for statistical computing and graphics. It compiles and runs on a wide variety of UNIX platforms, Windows and MacOS. To download R, please click on this link and choose your preferred CRAN mirror.
The purpose of this package is to estimate a summary survival curve from the survival rates and numbers of at-risk individuals extracted from studies of a meta-analysis. Survival probabilities have to be extracted at the same set of points in time for all studies. Missing data are not allowed. Studies included in the meta-analysis can have different follow-up durations. For a study ending after the time t, all survival probabilities until t have to be entered in data.
Input data are sorted by study and by time. As an example, we proposed a data frame with the data extracted from a meta-analysis by Cabibbo et al. (Hepatology, 2010).
