Persistent inflammatory activation in people living with HIV. Involvement in atherosclerosis.
Article in Frontiers in medicine, 2025. The graph could read no effect estimate from its abstract, so it casts no vote on the map. Cited by 4 papers.
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
Background: An increased prevalence of atherosclerosis has been observed in people living with HIV (PLWH). This study aimed to analyze levels of inflammatory, immune, endothelial, platelet, and coagulation parameters, as well as their relationship with subclinical atherosclerosis. Methods: A total of 120 PLWH with chronic infection and undetectable HIV load, along with 30 age- and sex-matched controls (HIV-uninfected individuals), were selected. Serum levels of proinflammatory molecules, including interleukin 6 (IL-6), soluble CD163, and high-sensitivity C-reactive protein, were measured. Additionally, neutrophil extracellular traps (NET)-derived parameters (anti-nucleosome antibody titers and myeloperoxidase concentrations), activated T lymphocytes, endothelial (E-selectin, vascular cell adhesion molecule 1), platelet (P-selectin, Platelet factor 4) and coagulation (D-dimer) markers were assessed. Cardiovascular risk factors were evaluated using the REGICOR and ASCVD risk estimators. In a subset of 61 individuals (18 controls and 43 PLWH), subclinical atherosclerosis was assessed by carotid Doppler ultrasound. Results: Levels of IL-6, sCD163, anti-nucleosome antibodies, and activated T lymphocytes were elevated in PLWH compared to controls. Likewise, serum levels of platelet factor 4 and D-dimer were higher in PLWH. Those PLWH with carotid atherosclerotic lesions exhibited higher REGICOR and ASCVD scores, as well as elevated IL-6 concentrations, compared to those PLWH without carotid atherosclerotic lesions. Multivariable analysis identified the REGICOR score and IL-6 serum levels as independent factors associated with atherosclerosis. Conclusion: People living with HIV with long-term viral load control exhibit increased levels of inflammatory, immune, platelet and coagulation markers. Subclinical atherosclerosis in this population is independently influenced by both classic cardiovascular risk factors and inflammatory activation.
