Preterm infants with gestational age &lt;32 weeks requiring a peripherally inserted central catheter for parenteral nutrition were included. The heparin group received parenteral nutrition with 0.5 IU\/ml heparin added for infusion through a peripherally inserted central catheter, whereas the nonheparin group did not receive heparin. Propensity score matching was used to balance baseline variables between the two groups. The primary outcome was the incidence of catheter\u2010related complications. A noninferiority margin of 10% was chosen. Nonelective catheter removal, heparin\u2010related side effects, and catheter dwell time were compared between the two groups.<\/jats:p><\/jats:sec><jats:sec><jats:title>Results<\/jats:title><jats:p>A total of 1089 very preterm infants were included. After propensity score matching, 432 infants from each group were analyzed. The incidence of catheter\u2010related complications was 22.9% in the heparin group and 21.8% in the nonheparin group, with an absolute difference of \u22121.16% (95% CI: \u22126.71% to 4.40%). The upper bound was below 10% (<jats:italic>P<\/jats:italic> for noninferiority\u2009&lt;\u20090.001), confirming noninferiority.
