Effect of sample vortex mixing on severe acute respiratory syndrome coronavirus 2 nucleic acid testing: Comparative analysis of individual samples and sample pools.
Article in The Journal of international medical research, 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
ObjectiveThis study investigated the effect of sample vortex mixing on the cycle threshold (Ct) values of severe acute respiratory syndrome coronavirus 2 (SARS-CoV-2) nucleic acid testing and further explored the underlying reasons for this effect.MethodsWe initially examined the impact of sample vortex mixing on Ct values. Subsequently, epithelial cells within the samples were quantified and stained using an improved Neubauer hemocytometer and Wright-Giemsa stain to elucidate the causative factors of Ct value changes. Finally, we expanded our sample size to validate the effect of vortex mixing on Ct values.ResultsWe observed a significant decrease in Ct values (all
