Development of RT-dPCR method and reference material for rotavirus G3P8 and G9P8.
Article in Analytical and bioanalytical chemistry, 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
The rotavirus (RV) is the predominant causative pathogen associated with acute gastroenteritis in children aged below 5 years, leading to an annual mortality rate of 200,000 infants globally. Despite the development of a vaccine, it exacerbates the medical burden around the world. Here, we have developed reverse transcription digital PCR (RT-dPCR) methods for precise and absolute quantification of nucleic acid in rotavirus G3P8 and G9P8. The pseudovirus reference material (RM) contained the RNA fragment encoding VP4 and VP7. The assigned values with expanded uncertainty were determined as (2432 ± 510) copies/μL and (3406 ± 613) copies/μL. The RM and RT-dPCR methods were employed to validate various digital platforms, revealing the inadequate performance of platform III, which could potentially result in "false-negative" outcomes. The application of RT-dPCR techniques and pseudovirus RM confers advantages in the diagnosis of RV-induced diseases, thereby enhancing the survival rate of young children suffering from acute gastroenteritis.
