1 · What the graph read from it

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.

2 · The registry

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

Hypertension is a major global health burden and a leading driver of cardiovascular disease, yet reliable blood-based biomarkers for early disease are still limited. We combined plasma proteomics with explainable machine learning to identify circulating proteins associated with stage 1 hypertension in the Qatar Biobank. Proteomic profiles from 778 participants (554 controls and 224 stage 1 hypertension cases) were analyzed; 1305 proteins were tested for differential expression with adjustment for age and sex, and top features were prioritized before training predictive models. Among the evaluated classifiers, CatBoost performed best (AUROC = 0.7985), and SHapley Additive exPlanations were used to interpret the model. We identified 36 proteins significantly associated with hypertension and observed a characteristic pattern featuring lower Renin, sRAGE, ghrelin, and IL-1RAcP, and higher TFPI, QORL1, HSP70, and C5a in hypertensive individuals. Pathway and network analyses implicated processes related to oxidative stress and vascular function. Together, these results demonstrate Renin, TFPI, sRAGE, QORL1, ghrelin, HSP70, IL-1RAcP, and C5a as candidate circulating biomarkers for hypertension and illustrate the value of explainable AI for translating proteomic signals into potentially clinically interpretable candidates, pending validation in independent and diverse cohorts.
