Association between renal function and arterial stiffness among women with systemic lupus erythematosus or antiphospholipid syndrome.
Article in Cardiology journal, 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
backgroundPatients diagnosed with systemic lupus erythematosus (SLE) or antiphospholipid syndrome (APS) carry a higher risk of atherosclerosis and subsequent major adverse cardiac events; however, the mechanisms of such complications are still not fully understood. Although patients with SLE or APS are also known to have an increased risk of renal function impairment, there are few data on the correlation of augmentation index normalized to 75 beats per minute (AI@75) or pulse wave velocity (PWV) reflecting arterial remodeling, with laboratory tests indicative of renal function in women diagnosed with SLE or APS.
methodsThis was a prospective, cross-sectional study that enrolled women with a diagnosis of SLE and/or APS. All patients underwent measurement of carotid-femoral PWV (SphygmoCor XCEL, AtCor Medical Ltd) with pulse wave analysis, calculation of AI@75, and laboratory assessment.
resultsA total of 60 women with SLE or APS were enrolled in the study. Urea level was found to correlate with AI@75 (rho = 0.362, p = 0.006) and PWV (rho = 0.487, p = 0.006). In separate adjusted (age, body mass index, and blood pressure) models, urea (B = 0.722, 95% CI: 0.407-1.037, p < 0.001), uric acid (4.932, 95% CI: 0.447-9.418, p = 0.03), creatinine (B for 0.1 mg/dL increase = 3.367, 95% CI: 1.112-5.601, p = 0.004), and eGFR (B = -0.318, 95%CI: -0.580- -0.055, p = 0.02) were associated with AI@75.
conclusionsUrea and uric acid values are associated with increased arterial stiffness measured by non-invasive methods such as PWV and AI@75 in women with SLE or APS with normal or slightly reduced glomerular function.
