Association of Neutrophil-to-Lymphocyte Ratio With All-Cause and Cardiovascular Mortality Among Individuals With Depression: A Large-Scale Cohort Study.
Article in Brain and behavior, 2025. The graph could read no effect estimate from its abstract, so it casts no vote on the map. Cited by 1 paper.
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
backgroundThe relationship between mortality in depressed patients and the neutrophil-to-lymphocyte ratio (NLR) is not well-documented.
methodsThis cohort study, involving 8749 individuals diagnosed with depression, was derived from the National Health and Nutrition Examination Survey (NHANES) 2005-2018. Data on mortality were obtained by linking the cohort database to the National Death Index, with updates available as of December 31, 2019. Various analytical techniques, including Cox proportional hazards models, restricted cubic splines, Kaplan-Meier curves, and subgroup and sensitivity analyses, were employed.
resultsDuring an average follow-up period of 84 months, 1023 participants (11.7%) died, with 271 of these deaths attributed to cardiovascular diseases (CVD). Our analysis demonstrated a positive connection among the NLR as well as mortality risk in all participants. In contrast to participants in the low NLR category (NLR ≤ 3.06), individuals belonging to the high NLR category (NLR > 3.06) exhibited a 64% increased risk of all-cause mortality (hazard ratio [HR] 1.63, 95% confidence interval [CI] 1.36-1.95) and a 144% elevated risk of mortality due to CVD (HR 2.44, 95%CI 1.77-3.36) after multivariate adjustment. The interactions and data stratification supported the credibility of our results. Importantly, we discovered notable interactions within subgroups that were differentiated by age and diabetes.
conclusionsElevated levels of the NLR are linked to a heightened risk of mortality from all causes, including CVD, among adults suffering from depression. This correlation is particularly pronounced in younger populations and in individuals who have diabetes.
