ABSTRACT
This paper summaries the Risk Of Bias In Non-randomized Studies-of Interventions (ROBINS-I),a tool for evaluating risk of bias about Non-randomized Studies-of Interventions (NRSI),and introduces the application of ROBINS-I in a published NRSI.According to the characteristics of NRSI,evaluation field and signaling question were designed in ROBINS-I to provide essential information about risk of bias for NRSI included in systematic reviews.ROBINS-I is the tool in assessment of risk of bias in observational studies and quasi-randomised studies.Although the tool hasbeen used in practice to some extent,but it still needs further improvement.Attention should be paid to its update and progress.
