Another 106 very low birth weight premature infants hospitalized from June 2024 to March 2025 were selected as the verification group. Lasso Logistic regression was used to screen for the predictors of PVL in very low birth weight premature infants. The nomogram risk prediction model was constructed. Hosmer-Lemeshow test and ROC analysis were used to evaluate the predictive value of the model. The decision curve analysis (DCA) was used to evaluate the clinical application value of the model.<\/jats:p>\n                  <\/jats:sec>\n                  <jats:sec>\n                    <jats:title>Results<\/jats:title>\n                    <jats:p>\n                      The total incidence of PVL in 354 premature infants was 23.73%. Lasso and logistic regression results showed that Apgar score at 1\u2005min after birth (OR\u2009=\u20090.645), C-reactive protein (CRP) (OR\u2009=\u20095.687), neonatal respiratory distress syndrome (NRDS) (OR\u2009=\u20095.412), sepsis (OR\u2009=\u20096.752), patent ductus arteriosus (OR\u2009=\u20099.428), and chorioamnionitis (OR\u2009=\u20098.342) were the predictors of PVL in very low birth weight premature infants (\n                      <jats:italic>P<\/jats:italic>\n                      \u2009&amp;lt;\u20090.05).
