Table 6. Descriptive summary of the available data from our included studies regarding the type B2 glenoid.
Asterisk (*) indicates that this data was not included in the weighted mean difference values given the lack of corresponding pre-operative data. Plus sign (+) indicates that this data was provided by the authors as mean differences as opposed to preoperative and postoperative data.
