Geospatial Distribution of HIV Seroprevalence Among Blood Donors in South Asian Countries: A Systematic Review and Meta-Analysis.

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
The reliance on replacement blood donors in developing countries has led to an increased prevalence of transfusion-transmitted infections (TTIs), including HIV. This systematic review and meta-analysis aimed to assess the seroprevalence of HIV among blood donors in South Asian countries and disseminate the findings in choropleth maps. In addition, gender-specific prevalence or the yearly trend of HIV prevalence among blood donors was also investigated. Following the PRISMA guidelines, we searched PubMed, Scopus, CAB abstracts, CINAHL, and Google Scholar for articles published between January 2000 and December 2022. The DerSimonian-Laird effect model was used due to the high heterogeneity of the data. Data analysis was performed using R Studio version 4.1.0, ArcGIS, and GraphPad Prism 7.0. The pooled seroprevalence of HIV among blood donors in South Asian countries was found to be 0.13%, with the highest prevalence of 0.19% in India and the lowest prevalence of 0.02% in Bangladesh and Bhutan. Female blood donors had a higher seroprevalence than their male counterparts (0.24%, vs. 0.17%). In contrast to voluntary blood donors with an HIV seroprevalence of 0.13%, replacement blood donors have a higher HIV prevalence of 0.26%. The observed high heterogeneity was attributed to variations in country, gender, type of blood donors, and study year. This study demonstrates a significant burden of HIV among blood donors in South Asia, emphasizing the need for enhanced donor screening protocols, targeted interventions and educational campaigns to ensure the safety of blood transfusion services. Future research should explore additional risk factors and focus on expanding screening methods, particularly in resource-limited settings.
