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
backgroundBlood transfusion is a life-saving intervention performed worldwide; however, it remains a significant public health concern due to the risk of transfusion-transmitted infections (TTIs). Globally, millions are infected with hepatitis B virus (HBV), hepatitis C virus (HCV), human immunodeficiency virus (HIV), and Treponema pallidum (syphilis) through unsafe blood transfusion practices. In resource-limited settings like Ethiopia, ensuring blood safety is especially challenging due to inadequate screening and surveillance systems. This study aimed to assess the prevalence and associated risk factors of HBV, HCV, HIV, and syphilis among voluntary blood donors in the North Gondar District Blood Bank, Northwest Ethiopia.
methodA retrospective cross-sectional study was conducted using data from 265 voluntary blood donors at the North Gondar District Blood Bank, collected between February 15, 2021, and May 24, 2022. Data were retrieved from the blood bank records between June 1 and June 15, 2022. Donor sociodemographic characteristics and transfusion-transmitted infection (TTI) screening results were extracted from these records. Descriptive statistics were used to estimate prevalence. Variables with a p-value < 0.25 in Bivariable analysis were included in a multivariable logistic regression model to identify independent predictors of TTIs. Multicollinearity was assessed using the variance inflation factor (VIF), and model fitness was evaluated using the Hosmer-Lemeshow goodness-of-fit test. A p-value < 0.05 was considered statistically significant.
resultThe study covered 265 blood donors in the Gondar blood bank district between February 15, 2021, and May 24, 2022. The total sero-prevalence of HIV, HCV, HBV and syphilis during the follow-up period was 2.26%, 2.64%, 4.53%, and 7.17%, respectively. Age groups of 26-35 for blood donors screening for HCV (AOR = 2.1, 95% CI 1.1, 3.29), Male donors (AOR = 1.2, 95% CI 1.10, 6.52), age groups of 26-35 for screening for HBV (AOR = 1.1, 95% CI 1.00, 1.24), age groups greater than 45 for screening for Treponema pallidum (AOR = 8.6, 95% CI 7.44, 10.02), and divorced marital status (AOR = 2.1, 95% CI 1.64, 6.94) were significantly associated with the prevalence of Sero-prevalence trans-fusion transmissible infections occurrence.
conclusionThis study found that the overall sero-prevalence of TTIs among blood donors in North Gondar was notable, with HCV (4.53%) and syphilis (7.17%) being the most prevalent. Statistically significant associations were observed between HCV and the 26-35 age group, syphilis and donors aged above 45, HBV and the 26-35 age group, male gender with TTIs, and divorced marital status with syphilis. These findings underscore the need for more targeted donor screening strategies focusing on these high-risk groups to enhance transfusion safety. Further studies with larger sample sizes are recommended to validate these associations and explore additional risk factors. CLINICAL TRIAL NUMBER: was not applicable in the study.
