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
Purpose: To assess the application value of bedside real-time ultrasound (US) for umbilical venous catheterization (UVC) in neonates and evaluate its safety and predictive factors for complications. Study design and methods: This was a single-arm, retrospective, observational study conducted at a single institution, without a direct internal control group (such as X-ray guided placement) for comparison. A total of 132 neonates who received UVCs using real-time US guidance with color Doppler were included. Clinical variables, including success rates and complications within 2 weeks post-insertion, were captured. Factors contributing to complications were identified using Multivariate Logistic Regression. An XGBoost model and SHAP analysis were employed to predict and interpret complication risks. Results: The success rate for one-time catheter insertion was 95.45%, the mean indwelling time was 7.31 ± 0.27 days, and the overall complication rate was 15.15%, with accidental catheter dislodgement occurring in 9.09% of cases. Independent risk factors for complications included non-standard catheterization, preterm birth, lower birth weight, and a lower 1 min Apgar score. The XGBoost model performed well in predicting complications, with SHAP analysis identifying non-standard technique and birth weight as predominant influences. Conclusion: Bedside real-time US is shown to be a safe and accurate procedure for UVC placement in neonates. While this study did not include a direct comparison group, the high success and low complication rates align with literature suggesting that US can improve accuracy and potentially decrease radiation exposure compared to routine X-ray verification. The observed improvements are inferred through comparisons with external literature; therefore, further randomized controlled trials are needed to quantify its superiority over X-ray guidance.
