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
Objective: Neutrophil-to-lymphocyte ratio (NLR), Platelet-to-lymphocyte ratio (PLR), Red-cell-distribution width (RDW) and Platelet-distribution width(PDW) have been proved to be related to the severity of a variety of diseases and poor prognosis. But their predictive value in neonatal pneumonia is still unknown. Therefore, this study explored the predictive value of NLR, PLR, RDW and PDW in the adverse prognosis of neonatal pneumonia. Methods: We retrospectively analyzed 132 neonates with pneumonia treated in our hospital from April 2022 to October 2024. At the same time, 50 healthy newborns delivered in our hospital during the same period were selected as the control group. The levels of NLR, PLR, RDW and PDW in children with different disease severity and prognosis were analyzed; The correlation between NLR, PLR, RDW, PDW levels and disease severity was analyzed, and the predictive value for the adverse prognosis of neonatal pneumonia. Results: Among 132 children, 65 were mild, 44 moderate and 23 severe; 26 cases had poor prognosis. The levels of NLR, PLR, RDW and PDW in children with different disease severity were significantly different (P<0.05). Spearman test showed that NLR, PLR, RDW, PDW were significantly positively correlated with the severity of neonatal pneumonia (P<0.05). Multivariate logistic regression analysis showed that NLR, PLR, RDW and PDW were the related factors influencing the poor prognosis of neonatal pneumonia (p<0.05). ROC curve analysis showed that the value of combined prediction of four indicators for poor prognosis of neonatal pneumonia was higher than that of single indicators, and the sensitivity of combined prediction was 100%, and the specificity was 94.9%. Conclusion: NLR, PLR, RDW, PDW were positively correlated with the severity of neonatal pneumonia, and the value of combined prediction of poor prognosis was higher.
