Propensity score analysis is a statistical technique that attempts to estimate the likelihood or probability of a subject being assigned to a specific treatment or group, given a set of observed covariates. When randomization is not possible, propensity score analysis can be used to create matched groups of cases that are similar on relevant characteristics. Therefore, propensity score analysis is recommended in this scenario.
