Proportions of patients with reinfection within 2 years after treatment in studies of one- and two-stage revision in unselected patients. N represents the total number of patients treated surgically, n represents the number of patients with reinfection. Cabrita a and b and Nelson a and b refer to randomised intervention and control groups, respectively. *Summary values for one-stage, two-stage and all studies (including studies with unselected patients with one- and two-stage revision; data not shown) were calculated using a random-effects model and the Freeman-Tukey arc-sine transformation to stabilise the variances.
