The Association Between Neonatal Respiratory Distress Syndrome and Plasma IgG N-Glycosylation: A Case-Control Study.
Article in Journal of inflammation research, 2025. The graph could read no effect estimate from its abstract, so it casts no vote on the map. Not yet cited in PubMed.
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
Background: Neonatal respiratory distress syndrome (NRDS) is the leading cause of neonatal death. Changes in plasma immunoglobulin G (IgG) N-glycosylation have been demonstrated in a variety of diseases. However, its implications and clinical significance in NRDS remain to be clarified. Methods: To determine the effect of IgG N-glycosylation on NRDS, we recruited 88 NRDS participants and 120 control participants from December 2021 to September 2022. Plasma was collected, IgG was isolated and purified, and the glycogram was analyzed by ultra performance liquid chromatography (UPLC) with fluorescence detector. Results: The occurrence of premature rupture of membranes (PROM) [OR=9.043(1.036-78.966), P=0.046] and the elevation of γ-glutamyltransferase (GGT) [OR=1.015(1.001-1.029), P=0.032] were independent risk factors for the occurrence of NRDS. Furthermore, the area percentages of GP1, GP3, GP4, GP11, GP13, and GP24 were significantly higher in NRDS patients compared with control group. Conversely, GP14 was observed to be significantly lower. Furthermore, an increase in plasma IgG sialylation and core fucosylation was observed in NRDS, whereas the modification with galactosylation was decreased. The model constructed using GP1, GP13, GP14, PROM, and GGT as composite indices demonstrated robust predictive performance (AUC=0.902, 95% CI: 0.851-0.953). Conclusion: Patients with NRDS frequently exhibit alterations in the glycosylation of plasma IgG. These findings provide new insights into the diagnosis of NRDS and clinical treatment.
