orsk: Converting Odds Ratio to Relative Risk in Cohort Studies with Partial Data Information

Reconstructs plausible 2 by 2 contingency tables from published cohort-study summaries when the original cell counts are unavailable. Given group sample sizes and an odds ratio with partial confidence interval information, the package searches for compatible event counts, then derives corresponding relative risks and confidence intervals. It implements the methods described in Wang (2013) <doi:10.18637/jss.v055.i05> and includes summary and plotting methods for reviewing admissible scenarios.
