Association between serum urea nitrogen levels and prostate-specific antigens (NHANES 2003-2010).
Article in Journal of health, population, and nutrition, 2024. 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
backgroundIncreasing evidence suggests that serum urea nitrogen may be a risk factor for prostate cancer (PCa) and influence serum prostate-specific antigen (PSA) concentrations, but direct evidence of a relationship between PSA and serum urea nitrogen levels in the general population is still lacking. The aim of this study was to demonstrate the relationship between serum urea nitrogen levels and prostate-specific antigen (PSA) and prostate cancer.
methodsWe conducted a cross-sectional study using the National Health and Nutrition Examination Survey (NHANES, 2003-2010) database. We performed a multifactorial regression analysis of the association between serum urea nitrogen levels and PSA and PCa, followed by subgroup analyses.
resultsA total of 5256 subjects were included in this study, and after adjusting for demographic, biological, and immunologic variables, we found that there was a threshold for blood urea nitrogen concentration below which every 1 ng/mL increase in serum urea nitrogen was associated with a 0.0325 ng/mL increase in PSA concentration (log2 transformed) (95% CI: 0.0064, 0.0586), and the P trend was was less than 0.05 and the difference was statistically significant. Sensitivity analyses using the generalized additive model (GAM) showed a linear relationship between serum urea nitrogen and serum PSA concentrations when blood urea nitrogen concentrations ranged from 0 ng/ml to 6.78 ng/ml.
conclusionSerum urea nitrogen was independently and positively correlated with serum PSA concentration when the concentration of serum urea nitrogen ranged from 0 ng/ml to 6.78 ng/ml.
