Fig. 2.
Funnel plot of the risk of recurrent instability after Bankart repair based on number of pre-operative instability episodes (one episode or multiple pre-operative instability episodes). There is no evidence of small study bias as indicated by inclusion of all study estimates (each of the 3 comparative studies in the meta-analysis are represented by a blue dot) within the 95% confidence limits (dashed lines). Additionally, Begg's test of small study bias was non-significant (p = 0.30).
