[Seroprevalence of infectious agents in blood donors and their components].
Observational study in Revista medica del Instituto Mexicano del Seguro Social, 2025. The graph could read no effect estimate from its abstract, so it casts no vote on the map. Cited by 2 papers.
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
Background: The seroprevalence of infectious agents in donors of blood and blood components is a relevant factor related to the biosecurity of blood components, therefore, the adequate choice of laboratory methods for screening, confirmatory and/or supplementary tests with high sensitivity and specificity. Objective: To estimate the seroprevalence of infectious agents transmitted by blood transfusion in blood donors during the period 2020 to 2023 at the CMN Siglo XXI Blood Bank. Material and methods: Descriptive, observational, retrospective study in 180,120 eligible blood donors and their components from the CMN Siglo XXI Blood Bank, between 18 and 65 years of age with reactive serology, during the period 2020-2023. The reactive serological markers of donors registered in the TESI-HEXABANK system and confirmatory/supplementary tests were analyzed. For the univariate analysis, Excel and SPSS version 26 were used. Results: The present study estimated that the seroprevalence of infectious agents transmitted by transfusion from 2020 to 2023 was 1.38% (n = 2489). The most seroprevalent marker was Treponema pallidum at 0.64%, followed by hepatitis C virus at 0.27%, human immunodeficiency virus at 0.19%, Trypanosoma cruzi at 0.15% and hepatitis B virus at 0.09%. Conclusions: The seroprevalence of transfusion-transmitted infectious agents allows us to visualize the regional epidemiological panorama of blood donors, which will generate new strategies for transfusion safety in recipients.
