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

objectiveTo estimate the number of additional years above chronological age ("brain-age gap") at which observed plasma neurofilament light chain (NfL) levels in cognitively unimpaired people with HIV (PWH) correspond to published age-stratified standards from cognitively unimpaired individuals in the general population.

designSecondary analysis of the multicenter observational cohort study (ACTG HAILO) involving older, cognitively unimpaired PWH on antiretroviral therapy (ART).

methodsPlasma NfL concentrations were quantified using the Quanterix® Simoa assay in 340 PWH aged ≥45 years. Values were compared with two age-stratified reference standards from cognitively unimpaired general-population controls. The brain-age gap was estimated using a generalized logistic model with repeated measures so that 5% of observed NfL concentrations in PWH would exceed the reference upper 95 th percentile for the imputed age.

resultsMedian plasma NfL concentration was 10.1 pg/mL (IQR: 7.4-13.5). Using Simrén et al. standards, 24.1% (95% CI: 19.8-29.0) of observed values exceeded the age-specific upper 95 th percentile, and 10.0% (95% CI: 7.2-13.7) using Bornhorst et al. standards. Model-based results suggested brain age was 11.0 years (95% CI: 9.1-13.7) or 6.4 years (95% CI: 5.1-8.5) higher than chronological age, depending on the standard. The estimated brain-age gap was significantly greater in individuals with subsequent cognitive decline than in those without (Simrén: 13.0 vs. 8.4 years; Bornhorst: 7.6 vs. 5.0 years).

conclusionPlasma NfL reflects a substantial brain-age gap in cognitively unimpaired PWH on ART, supporting evidence of advanced aging. The brain-age gap was higher in PWH with subsequent cognitive decline.
