2.7. Bias risk and quality assessment
To assess the risk of bias and quality of each of the included studies, the tool was used Joanna Brigs Institute (JBI)19,20. Two authors (R.P.V. and N.L.C.G.). independently assessed all studies, and any disagreements were resolved by mutual discussion. The JBI presents four assessment options: ”Yes, No, Unclear, and Not applicable”. In addition, affirmative responses are summarized from 0 to 8. Articles with a score below 4 are considered low quality and those with a score above 4 are considered high quality.
