In observational studies subjects are not randomly assigned to treatment and control groups. Therefore, both groups can be significantly different from each other and their differences after applying a treatment cannot be attributed to the treatment effect. Propensity scores methods offer a way to balance groups by matching treatment and control units based on a set of covariates. This paper ex...

This criterion is widely discussed in textbooks and is often mentioned in empirical papers. At the same time, it is well known throu...

Whilst there are multiple ideas on how to reduce publication bias, only a minority of journals have made substantive changes to address the problem.
