Lack of Association Between Sodium Intake and Cytokine Levels.
Article in Integrated blood pressure control, 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
Purpose: The complex pathogenesis of hypertension, potentially involving inflammatory pathways, remains elusive. This study aimed to evaluate the relationship between 24-hour urinary sodium excretion and inflammatory cytokines alongside C-reactive protein (CRP) in a nationwide Finnish sample. Materials and methods: 265 participants from the FINRISK 2002 study were included in the analyses. Multivariable-adjusted associations of 24-hour urinary sodium with circulating CRP and 26 cytokines were examined. Results: 24-hour urinary sodium was not significantly associated with any of the cytokines or CRP (p ≥ 0.02 for all, significance at <0.001). Adjustments for age, sex, serum creatinine concentration, and alcohol intake did not alter these results. Conclusion: This cross-sectional study revealed no associations between 24-hour urinary sodium and cytokine or CRP levels. This does not suggest reducing salt intake would be unbeneficial in hypertension. Additional research is required to clarify the mechanisms through which salt may induce hypertension. Assessing sodium intake in epidemiological studies is also challenging.
