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

backgroundPremature atherosclerosis has been observed among people with HIV (PWH) with high risk of cerebrovascular disease. The aim of this study was to evaluate premature atherosclerosis in young PWH with and without ischemic stroke.

methodsWe 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) with PWH without a history of stroke (controls) matched (1:2) for age, sex and race. Premature atherosclerosis was assessed using a Mindray DC-40, linear probe 8-13 MHz high resolution B-mode ultrasound to measure carotid intima-media thickness (cIMT; abnormal≥0.70 mm) and pulse wave velocity (PWV; abnormal≥10.00m/s).

resultsWe analyzed results for 50 cases and 100 controls. Compared to controls, cases were more likely to have traditional stroke risk factors such as hypertension (42 % vs. 1 %, p=0.001); shorter duration from HIV diagnosis (<3 months: 16 % vs. 1 %, p=0.001);and markers of atherosclerotic disease, including higher PWV [10.89 (9.99-12.15) m/s vs. 8.97 (8.16 - 9.54) m/s, p<0.001] and increased cIMT [0.79 (0.70-0.99) mm vs. 0.63 (0.58 - 0.67) mm, p<0.001]. Poor WHO HIV clinical stage (stage 3: aOR 58, 95 % CI 1-3213, p=0.04), higher PWV (aOR 8.7, 95 % CI 2.0-38.1, p=0.004) and urban residence (aOR 25.5, 95 % CI 1.6-413.4, p=0.02) were independently associated with ischemic stroke in multivariable analyses.

conclusionIn this cohort of young-onset HIV-associated non-cardioembolic ischemic stroke, premature atherosclerosis, as indicated by higher PWV, was independently associated with stroke.
