Association of renal resistive index with coronary artery calcification in patients with preserved renal function.
Article in Journal of ultrasound, 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
purposeTo investigate whether renal resistive index (RRI) is independently associated with the presence of coronary artery calcification in patients with preserved renal function undergoing coronary computed tomography angiography (CCTA), and to explore its unadjusted associations with continuous coronary artery calcium score (CACS) and Coronary Artery Disease Reporting and Data System (CAD-RADS) categories.
methodsThis prospective cross-sectional study included 120 patients with preserved renal function who underwent renal Doppler ultrasonography before CCTA. The primary outcome was the presence of coronary artery calcification, defined as a CACS > 0. Associations of RRI with continuous CACS and CAD-RADS categories were evaluated in exploratory, unadjusted analyses. Multivariable logistic regression evaluated the independent association between RRI and CACS > 0. A clinical model and the same model supplemented with RRI were compared using receiver operating characteristic analysis.
resultsRRI was higher in patients with CACS > 0 than in those with CACS = 0 (0.697 ± 0.051 vs. 0.646 ± 0.054, p < 0.001) and correlated with CACS (r = 0.474, p < 0.001). RRI also differed across CAD-RADS categories (p < 0.001). After adjustment for age, sex, hypertension, diabetes mellitus, smoking, and dyslipidaemia, each 0.01-unit increase in RRI was independently associated with higher odds of CACS > 0 (adjusted OR 1.137, 95%CI 1.041-1.242; p=0.005). Adding RRI improved model fit (likelihood-ratio p=0.003) but did not significantly improve discrimination (AUC 0.782 vs. 0.819; DeLong p = 0.129).
conclusionRRI was independently associated with the presence of coronary artery calcification in patients with preserved renal function. Associations with continuous CACS and CAD-RADS categories were exploratory and unadjusted.
