Development and validation of a nomogram for predicting necrotizing enterocolitis in premature infants with early-onset sepsis.
Article in Scientific reports, 2025. The graph could read no effect estimate from its abstract, so it casts no vote on the map. Cited by 2 papers.
What it found
Each row is one number read from the abstract, on the scale the paper reported it, with its interval. Left of the dashed line favours the treatment, right favours the comparator. Under each row is the sentence it came from. New to these charts? A ten-minute tutorial.
The abstract states no effect estimate the extractor could read, or names no intervention and outcome on the map, so this paper lights no cell and moves no belief. It is still indexed, cited and linked below.
The trial behind it
Trials whose registry record cites this paper, or whose number appears in the abstract. A trial that started after this paper was published is citing it as background, not reporting it.
Neither the registry nor the abstract names a trial number. If this is a trial report, that itself is worth knowing.

Abstract
This study aimed to develop an effective individualized predictive nomogram for the occurrence of necrotizing enterocolitis (NEC) in premature infants with early-onset sepsis (EOS). A total of 238 premature infants meeting the inclusion criteria of gestational age < 37 weeks and EOS diagnosis, including 71 with NEC and 167 without NEC (NEC incidence: 29.8%), treated at the First Hospital Affiliated to Army Medical University from January, 2016, to September, 2024 were retrospectively enrolled as a modeling cohort. Additionally, 205 preterm with EOS (53 with NEC and 152 with non-NEC, NEC incidence: 25.9%), who were treated at Liaocheng People's Hospital from January, 2014, to September, 2024 were retrospectively enrolled as a validation cohort to assess the predictive efficacy of the model. LASSO-Logistic regression analysis were applied to screen independent predictors, which were subsequently incorporated into a nomogram constructed using R software. Model performance was assessed through receiver operating characteristic analysis, calibration curves, decision curve analysis (DCA), and clinical impact curves (CIC). Lasso-logistic regression identified four independent predictors of NEC in premature infants with EOS: chorioamnionitis (OR = 3.07, 95% CI: 1.26-7.48, p = 0.013), neonatal respiratory distress syndrome (OR = 2.20, 95% CI: 1.10-4.41, p = 0.027), lactate level (OR = 1.96, 95% CI: 1.48-2.58, p < 0.001), and white blood cell (WBC) count (OR = 0.89, 95% CI: 0.83-0.95, p < 0.001). These factors were integrated into the nomogram. The nomogram demonstrated excellent discriminative ability with the area under the receiver operating curve of 0.848 (95% CI: 0.793-0.903, sensitivity: 0.820, specificity: 0.761) in the modeling cohort and 0.825 (95% CI: 0.764-0.887, sensitivity: 0.750, specificity: 0.755) in the validation cohort, enabling early risk stratification for targeted clinical monitoring. Calibration curves confirmed good agreement between predicted and observed NEC probabilities (modeling cohort: χ
