Co-allosteric hairpin probe for detecting microRNA with high specificity.
Article in RSC advances, 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
MicroRNAs have emerged as crucial biomarkers for disease diagnosis and prognosis, while their accurate detection remains challenging due to high sequence homology among family members. In this study, a co-allosteric hairpin (CA-HP) probe was designed for highly specific microRNA detection. The CA-HP probe leverages synergistic interactions between the target miRNA and a helper strand to induce a conformational change, resulting in fluorescence activation only upon perfectly matched target recognition. By optimizing the complementary lengths of the target and helper strands, the system achieves significantly enhanced specificity compared to conventional hairpin probes. This strategy offers a robust and facile approach for accurate miRNA profiling, which is crucial for clinical diagnostics and personalized medicine. The CA-HP design also provides a generalizable framework for developing high-specificity nucleic acid probes.
