Hematological inflammatory indices and their relationship to the risk of hypertension.
Article in Epidemiology and health, 2026. 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
objectivesChronic inflammation has been implicated in the development of hypertension in numerous previous studies. However, evidence regarding the association between hematological inflammatory indices derived from complete blood count tests and the long-term risk of hypertension remains limited. Therefore, this study aimed to investigate the association between various hematological inflammatory indices and the risk of incident hypertension in a large cohort study.
methodsWe analyzed data from a large Korean cohort (n=128,241). The incident risk of hypertension was evaluated according to quartiles of the neutrophil-to-lymphocyte ratio (NLR), monocyte-to-lymphocyte ratio (MLR), platelet-to-lymphocyte ratio (PLR), systemic immune-inflammation index (SII), and systemic inflammatory response index (SIRI) using Cox proportional hazards models. Additional analyses were conducted for high-sensitivity C-reactive protein (hsCRP) levels and stratified by gender.
resultsDuring a median follow-up of 6.8 years, 18,503 participants (14.4%) developed hypertension. Higher quartiles of SII, SIRI, and NLR were significantly associated with an increased risk of incident hypertension in both genders. PLR showed a clearer positive association in women, whereas MLR demonstrated only marginal associations. These patterns were consistent with the associations observed for hsCRP.
conclusionsThese findings suggest that elevated hematological inflammatory indices above certain thresholds are associated with an increased risk of hypertension, even among young and generally healthy individuals.
