Plasma apolipoprotein E and monocyte chemoattractant protein-1 levels in young people with HIV and ischemic stroke in Lusaka, Zambia.
Article in Frontiers in stroke, 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
Background: Apolipoprotein E (ApoE) and monocyte chemoattractant protein-1 (MCP-1) are inflammatory markers associated with premature atherosclerosis, which leads to increased cardiovascular disease risk among people with HIV (PWH). We aimed to evaluate the association between the plasma levels of these inflammatory markers and ischemic stroke in young PWH. Methods: We conducted a prospective case-control study at the University Teaching Hospital in Lusaka, Zambia, between March 2022 and October 2024, comparing young PWH with non-cardioembolic ischemic stroke (cases) to age- and sex-matched PWH without a history of stroke (controls). Standardized data collection instruments were used to collect information on other known risk factors for stroke, including demographic, clinical, laboratory, and imaging parameters. ELISA was done to measure ApoE and MCP-1 levels in the plasma of individuals in both the case and control groups. Results: We analyzed results for 50 cases and 50 controls. Compared to controls, cases were more likely to have (1) traditional stroke risk factors such as hypertension (42 vs. 2%, Conclusion: The results suggest that lower plasma ApoE levels are independently associated with non-cardioembolic ischemic stroke in young PWH. Additional studies with larger sample sizes are needed to further explore the contribution of these inflammatory markers in young-onset HIV-associated stroke.
