“…However, domain 6 was particularly heterogeneous for the no information reported or different methods used to assess outcomes in different intervention groups. Nine out of fourteen studies were assessed as "moderate" risk of overall bias [5,17,[24][25][26]28,29,32,35], while two were determined to have a "serious" risk [27,31], and three a "critical" risk [30,33,34]. Regarding the bias due to confounding, nine out of fourteen studies were evaluated as having a "moderate" risk [5,17,[24][25][26]28,29,32,35]; differently this risk was higher as "serious" in studies performed through insurance surveys or databases [31,34], or "critical" in single team experiences [30,34] or Justice Court [27].…”
