Fig. 4. Results of sensitivity analysis are shown in this figure. (A) Maturation failure of one-stage brachio-basilic vein fistulas (BBVFs) was significantly worse compared to two-stage BBVFs and (B) similarly two-stage BBVFs were less likely than one-stage BBVFs to lose their functional secondary patency. (C) Long-term complications (excluding postoperative events) showed a non significant trend to occur more often with one-stage BBVFs than two-stage BBVFs, (D) however all complications were significantly more likely to occur with one-stage BBVFs compared to two-stage BBVFs. RR, risk ratio; M-H, Mantel-Haenszel; CI, confidence interval; df, degrees of freedom.
