Odds ratios estimation using the prognostic score

What is it about?

Introduced by Hansen in 2008, the prognostic score (PGS) has been presented as ‘the prognostic analogue of the propensity score’ (PPS). Using Monte-Carlo simulations, this paper evaluates the ability of existing and new PGS-based methods to estimate the conditional and marginal odds-ratios in the context of observational studies, and compares these methods with PPS-based methods in various settings.
