The systemic immune-inflammatory index in high-risk patients with hypertension: a cross sectional-study.
Article in Sao Paulo medical journal = Revista paulista de medicina, 2025. 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
introductionEssential hypertension is an important health condition responsible for conditions such as heart attack, stroke, and kidney disease. Traditional risk factors and their control are important for reducing mortality. Inflammation caused by organ damage plays a role in the undesirable outcomes of hypertension. Biomarkers, such as the systemic immune-inflammatory index (SII), are predictors, but their relationship with risk factors is poorly understood.
objectiveTo evaluate the correlation between the SII and risk factors in patients with hypertension.
methodsThis cross-sectional study was conducted in 2020 in Bahia with hypertensive patients from an outpatient clinic. We collected demographic and clinical data such as age, body mass index, and the following biomarkers: low-density lipoprotein level, glomerular filtration rate, interleukin 6 level, C-reactive protein level, neutrophil/lymphocyte ratio (NLR), hemogram, creatinine level, urea level, ferritin level, and vitamin D level.
resultsA total of 61 patients, most of them black women, participated in the study. The prevalence of type 2 diabetes was 19%, and there was no prevalence of stroke or heart attacks. According to the Framingham risk index, a large part of the sample presented high and very high risks. The bivariate analysis between SII and NLR was positive. Multivariate analysis showed that age, renal function, and NLR were positively correlated with the SII. The patients' Framingham risk did not correlate with the SII.
conclusionsInflammation is important for vascular damage in arterial hypertension caused by increased oxidative stress. We evaluated SII and NLR as indices of correlation with risk factors. The SII is a lowcost tool that can be used to screen for chronic conditions, such as hypertension. In summary, higher SII was positively associated with older age and worse renal function in patients with high-risk hypertension.
