Kaposi's sarcoma herpesvirus seroprevalence among blood donors in Uganda.
Article in Transfusion, 2025. The graph could read no effect estimate from its abstract, so it casts no vote on the map. Cited by 1 paper.
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
backgroundKaposi's sarcoma herpesvirus (KSHV) causes a life-long infection that can progress to several types of KSHV-associated diseases. There is evidence for transfusion transmission of KSHV. In endemic regions, such as sub-Saharan African, KSHV seroprevalence is >40%. However, previous studies of blood donors utilized immunoassays that detect KSHV-associated disease-specific antigens, which may underestimate the true burden of KSHV in a healthy population. STUDY DESIGN AND
methodsWe utilized samples from an on-going transfusion transmitted infection clinical trial to estimate the seroprevalence of KSHV among 4921 blood donations from healthy donors in Uganda collected between October 2019 and December 2022. A multiplexed bead-based assay was used to measure plasma IgG against five antigens encoded by the K8.1, K10.5, ORF73, ORF38, and ORF25 genes of KSHV. Significant associations between donor characteristics and seroprevalence were assessed by chi-square tests.
resultsOverall, KSHV seroprevalence was 69.1%. Seroprevalence was higher in units collected from older donors compared with younger donors and male donors (71.9% [95% confidence interval (CI) = 70.4%-73.3%]) compared with female donors (61.3% [95% CI = 58.6%-64.0%]; p < .001). KSHV seroprevalnce was higher among units collected from donors positive for T. pallidum (82.5% [95% CI = 73.8%-89.3%]) compared with units collected from donors who were negative (68.8% [95% CI = 67.5%-70.1%]; p < .001). KSHV seroprevalence was higher in units that tested positive for HIV, HBV, or HCV, though these results were not statistically significant.
conclusionGiven the high seroprevalence and limited availability of lab assays that detect active KSHV infections, methods such as leukoreduction or pathogen reduction should be considered to potentially reduce the risk of transfusion transmission of KSHV.
