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 donor selection is a crucial stage in reducing the risk of transfusion-transmissible infections (TTIs) and ensuring the safety of blood components. The objective of this study is to evaluate the impact of each question regarding deferral reasons on the risk of TTIs.
methodsThis study was conducted in twenty blood transfusion centers between March 1, 2018, and September 30, 2019, including high-risk deferred volunteers from seven different groups. All samples from deferral volunteers were screened for HBsAg, anti-HCV, and HIVAg/Ab. Negative samples were pooled and tested for HBVDNA and HCVRNA. The results were compared with those of eligible donors. The association between high-risk behaviors and TTIs was analyzed using risk ratios and 95% confidence intervals.
resultsOut of 2525 high-risk deferred volunteers, the risk of TTIs based on deferral reasons was as follows: a history of positive results of infectious tests RR: 401.6 ( 95% CI : 276.7‒582.8), drug abuse RR: 133.3 (61.9‒287.0), exposure to someone else's blood RR:39.8 (5.7‒275.3), high-risk procedures RR:14.3 (7.9‒25.9), unsafe sexual behaviors RR:9.03 (4.1‒20.1), imprisonment and medical interventions RR=0.0. The deferred group had significantly higher rates of viral markers compared to eligible donors. Furthermore, one reactive HCV RNA was detected in anti-HCV negative samples.
conclusionThis study showed that deferring blood donations based on a history of positive results from infectious tests, drug abuse, unsafe sexual behaviors, exposure to someone else's blood, and high-risk procedures is effective for ensuring blood safety. These deferral practices should be maintained. We recommend that other deferral criteria should be regularly evaluated for effectiveness.
