%description
Performs Trial Sequential Analysis (TSA) for meta-analyses of
time-to-event outcomes reported as hazard ratios. Implements the
Schoenfeld required-events sample-size formula generalised for unequal
allocation, the Diversity (D-squared) heterogeneity adjustment of
Wetterslev et al. (2009), and O'Brien-Fleming-type alpha- and
beta-spending trial sequential monitoring boundaries computed at the
inverse-variance information based on observed study-level log-HR standard
errors (not merely event counts), via a compiled (C++) recursive numerical
integration engine ported from the R package 'RTSA' (Soerensen, Olsen,
Lange and Gluud; an R implementation of the Trial Sequential Analysis
software of the Copenhagen Trial Unit, <https://ctu.dk/tools>), with no
fixed software-imposed limit on the number of looks (subject to available
computational resources). Produces a cumulative Z-curve plot with
efficacy, futility, and conventional significance boundaries. Methodology
follows Miladinovic et al. (2013) <doi:10.1016/j.jclinepi.2012.11.007> and
Wetterslev et al. (2009) <doi:10.1186/1471-2288-9-86>.
