Detecting and correcting the bias of unmeasured factors using perturbation analysis: a data-mining approach

BACKGROUND: The randomized controlled study is the gold-standard research method in biomedicine. In contrast, the validity of a (nonrandomized) observational study is often questioned because of unknown/unmeasured factors, which may have confounding and/or effect-modifying potential. METHODS: In thi...
