Figure 9. Risk of composite stone recurrence, allopurinol versus control treatment. This figure depicts the risk of composite stone recurrence in patients assigned to allopurinol versus control. Two studies totaling 152 patients are represented in this forest plot. Risk of composite recurrence was significantly reduced by 41% with citrate therapy compared to control (Risk ratio was 0.59 [95 percent confidence intervals 0.42 to 0.84]). Incidence of recurrence was 33 percent for the allopurinol group versus 55 percent for the control group.
