Forest plots of the included studies using the Sonoma CRx reporting on (a) Constant-Murley score at 12 months, (b) Disabilities of Arm, Shoulder and Hand Score at 12 months, (c) cosmetic dissatisfaction, (d) hardware failure, (e) infection, and (f) nonunion. Forest plots display the mean functional outcome (a and b) or proportion of complications (c-f), 95% confidence interval and the relative weight of the individual studies. The diamond indicates the pooled estimate and its 95% confidence interval. The red bar indicates the 95% prediction interval. Prediction intervals illustrate which range of true effects expected to occur in similar studies in future settings
