Table 3 Subgroup analysis for the complications by BMI (Percutaneous versus Surgical)

From: Percutaneous insertion of peritoneal dialysis catheter is a safe and effective technique irrespective of BMI

  1. Variables are presented as number and percentage (if number is not 0). The percentage is the proportion of complications in the relevant subgroup. Subgroup analysis was performed by stratified chi-square test. The upper half of the table is non-infectious complications, and the lower half is infectious complications. Both non-infectious and infectious complications are divided into three parts, i.e., early stage, late stage and total. Early was defined as complications occurred within 30 days after catheter insertion (for non-infectious), or 2 weeks after insertion (for infectious). Bleeding means only severe conditions when demanding transfusion or surgical hemostasis. Catheter related infection consists of exit site and tunnel infections. Subgroup A: data in the two columns of BMI > 28, subgroup B: data in the two columns of BMI ≤ 28. BMI Body mass index
