Late diagnosis of paediatric HIV infection in high-income countries: Lessons from the HIV Perinatal Virtual Clinic.
Article in HIV medicine, 2026. 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
introductionTimely diagnosis of HIV in children remains a challenge in all settings including low-prevalence, high-income countries (HIC). We aimed to characterize the prevalence of late diagnosis, and prior missed diagnostic opportunities among new presentations of paediatric HIV in HIC referred to an international Perinatal Virtual Clinic (PVC).
methodsRetrospective analysis of new paediatric diagnoses in HIC, referred to the PVC between January 2018 and April 2025. Data on demographics, clinical features and HIV virology/immunology were extracted from standardized referral templates. Cases were categorized as late or non-late diagnosis by age-related CD4 thresholds, and the two groups compared.
resultsAmong 45 new paediatric HIV diagnoses referred to the PVC from the European region (41), Australia (2) and Chile (2), the median age was 9 years (IQR 0.8-13); 66% (27/41) were migrants, predominantly from sub-Saharan Africa; 39% (16/41) were born in HIC. Most (27/45;60%) were tested due to symptoms; 21/45 (47%) were diagnosed with AIDS. The median CD4 count was 230 cells/mm
conclusionsDespite access to prevention and screening, late paediatric HIV diagnosis persists in HIC, with severe immunosuppression and missed opportunities for earlier recognition and treatment initiation. Improved implementation of family-based screening, particularly following parental/sibling diagnosis or migration from endemic areas, and education of healthcare providers regarding HIV indicator diseases in children are essential.
