Association between cerebrospinal fluid CXCL10 and neurocognitive disorders in people living with HIV: a meta-analysis.
Synthesis in AIDS research and therapy, 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
backgroundC-X-C motif chemokine ligand 10 (CXCL10) is implicated in HIV-associated neuroinflammation, yet its association with HIV-associated neurocognitive disorders (HAND) remains unclear. We conducted a meta-analysis to evaluate cerebrospinal fluid (CSF) CXCL10 differences between people living with HIV (PLWH) with and without HAND and to assess the odds of HAND in relation to high versus low CSF CXCL10 levels.
methodsPubMed, Embase, and Web of Science were systematically searched. Observational studies reporting CSF CXCL10 levels in adult PLWH with and without HAND were included. Standardized mean difference (SMD) and odds ratio (OR) were pooled using random-effects models accounting for the potential influence of heterogeneity.
resultsEleven studies involving 1,536 PLWH were included. Compared to those without HAND, PLWH with HAND had significantly higher CSF CXCL10 levels (SMD: 0.56, 95% CI: 0.17-0.96; p < 0.001), with high heterogeneity (I² = 86% and τ² = 0.31). The 95% prediction interval (PI: - 0.78 to 1.91) indicated substantial between-study variability. Subgroup analyses showed significantly greater CXCL10 elevation in studies with ≤ 50% ART coverage (SMD: 0.90 vs. 0.17; p = 0.04) and in those evaluating HIV-associated dementia (SMD: 1.45 vs. 0.37; p < 0.001). Meta-regression did not identify any statistically significant moderators, although ART proportion and CD4 + count explained 29.2% and 25.6% of the variance, respectively. No significant association was found between high CSF CXCL10 and HAND (OR: 1.41, 95% CI: 0.90-2.22; p = 0.13).
conclusionElevated CSF CXCL10 may be associated with HAND in PLWH, particularly among ART-naïve individuals and in more severe cognitive impairment. However, substantial heterogeneity and a wide PI suggest that the strength of this association varies across populations. CSF CXCL10 remains a promising but not definitive biomarker for HAND risk stratification.
