Temporal trends in transfusion-transmissible infections among blood donors in Jordan: A large-scale Amman-based surveillance update (2018-2019).
Observational study in Medicine, 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
Transfusion-transmissible infections (TTIs) remain a global concern in blood safety. This study presents the largest Amman-based dataset on Royal Medical Services donors since 2016 (n = 49,296 donations) and the first to apply a monthly Chi-square (χ2) trend analysis for TTI surveillance in Jordan. Blood donations collected between July 2018 and December 2019 were screened for hepatitis B surface antigen (HBsAg), hepatitis B core antibody (HBcAb), hepatitis C virus antibody (HCV Ab), human immunodeficiency virus (HIV) 1/2 antibodies, and Treponema pallidum using electrochemiluminescence assays, followed by confirmatory enzyme-linked immunosorbent assay tests. HBcAb was detected in 3.44% of donors, HBsAg in 0.41%, and HCV Ab in 0.10%. No confirmed cases of HIV or syphilis were found. These rates are lower than previously reported national estimates, suggesting a continued decline in hepatitis B virus and hepatitis C virus (HCV) prevalence. Chi-square tests revealed significant monthly variation for HBcAb (P < .001) and HBsAg (P < .001), while HCV trends were not significant. The majority of donors were male (98.2%) and from Amman (98.24%), limiting national generalizability. Although the dataset predates the COVID-19 pandemic and is geographically constrained, it remains the most recent and comprehensive post-2016 dataset available for national TTI surveillance. This study highlights low national TTI prevalence and underscores the value of blood donor screening as a tool for public health surveillance, especially in refugee-hosting contexts. The application of temporal analysis enhances its relevance for infection monitoring and health policy. Findings support the integration of seasonal trend surveillance into Jordan's national blood safety strategy and align with global goals to eliminate communicable diseases by 2030.
