Identifying risk factors and donor characteristics for vasovagal reactions in whole blood donation: Insights and safety recommendations from a northern Indian study.
Article in Asian journal of transfusion science. 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
backgroundAlthough adverse reactions and injuries associated with blood donation are typically self-sustaining, they may defer donors from making future blood donations.
aimsThis study aimed to determine the prevalence and predictors of adverse reactions in whole blood donors, thereby identifying potential targets for interventions to reduce such events.
methodsA total of 5,003 whole blood donations were analyzed over a two-year period. Donor demographic, medical, and biometric parameters were recorded and examined for associations with adverse donor reactions.
resultsThe overall prevalence of vasovagal reactions was 1.7% and 287 donors (5.74%) experienced adverse events (AEs). Strong predictors of adverse reactions included younger age, first-time donation, low body weight, donation around noon, and a pre-donation waiting period exceeding 30 minutes. Vasovagal reaction rates reported in the literature vary widely, ranging from 0.09% to 2.24%. Most studies, including the present one, found no significant gender differences in reaction rates; in this study, males and females experienced almost similar rates (1.7% vs. 1.8%).
conclusionThese findings are instrumental in identifying donors at greater danger of developing undesirable reactions. Enhanced monitoring during and after donation, along with timely intervention, may facilitate to prevent many of these adverse and unpleasant events and improve donor retention.
