Association between platelet-to-lymphocyte ratio and blood urea nitrogen levels in pediatric populations: evidence from the NHANES (2009-2018).

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: Blood urea nitrogen (BUN) reflects renal function and protein metabolism, while the platelet-to-lymphocyte ratio (PLR) is a common inflammatory marker. Though studied in adults, their relationship with children is unclear. This study aims to explore this association in children aged 12-18 years using National Health and Nutrition Examination Survey (NHANES) 2009-2018 data and evaluate PLR as a potential non-invasive marker for renal function. Methods: Given the physiological differences between children and adults, this study utilized data from the NHANES to explore the association between PLR and BUN levels in a pediatric population. This cross-sectional study used NHANES data collected between 2009 and 2018. A total of 2,086 participants were included after excluding individuals with missing data or an age range beyond 12-18 years. Results: A significant negative correlation between PLR and BUN was found in this study, which remained consistent even after adjusting for a wide range of variables (P<0.001). Subgroup analyses further confirmed the robustness of this association across sex, race, and body mass index categories. Restricted cubic spline analysis revealed a significant non-linear negative association with an inflection point at PLR of 118.45. The decline in BUN levels became more pronounced when PLR exceeded the threshold. Conclusions: This study demonstrated a negative correlation between PLR and BUN levels in children, suggesting that PLR could be used as a potential non-invasive marker for assessing renal function. More large-scale prospective studies are needed to substantiate our findings.
