Prevalence of Loneliness and Social Isolation Among People Living With HIV: A Systematic Review and Meta-Analysis.
Synthesis in Journal of clinical nursing, 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
aimTo estimate the prevalence of loneliness, social isolation, and their co-occurrence among people living with HIV and to explore factors explaining heterogeneity between estimates.
designA systematic review and meta-analysis. DATA SOURCES: PubMed, Cochrane Library, SciELO Citation Index (via Web of Science), Scopus, Embase, PsycArticles, and Cumulative Index to Nursing and Allied Health Literature (CINAHL) were searched from inception until November 1, 2024 for relevant studies.
methodsStudy eligibility, data extraction, and methodological quality assessment were conducted independently by two reviewers. Random-effects meta-analysis was used to estimate pooled prevalence. Subgroup analyses were performed.
resultsA total of 66 studies were included. The pooled prevalence of loneliness was 46.9% and that of social isolation was 25.9%. However, heterogeneity was very high across studies, and these pooled estimates should therefore be interpreted cautiously. Subgroup analyses suggested regional variation in both loneliness and social isolation. Other subgroup findings should be interpreted cautiously because some subgroup estimates were based on small numbers of studies.
conclusionLoneliness and social isolation are highly prevalent among people living with HIV. Population-specific intervention strategies are needed to reduce this burden, and future studies should further examine contextual and demographic differences to guide intervention design. IMPLICATIONS FOR THE PROFESSION AND/OR PATIENT CARE: Routine HIV services should include screening and referral pathways for loneliness and social isolation. IMPACT: This systematic review identified the pooled prevalence of loneliness and social isolation among people living with HIV, highlighting a substantial and clinically relevant burden. The findings may influence HIV nurses' practice and inform care approaches for other clinical populations experiencing loneliness and social isolation. REPORTING
methodThis systematic review followed the PRISMA and MOOSE reporting guidelines. PATIENT OR PUBLIC CONTRIBUTION: No patient or public contribution.
