Selective electrochemical discrimination of 3' isomiRs differing by two nucleotides.
Article in The Analyst, 2026. 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 and isomiRs are promising biomarkers for the detection of diseases such as cancers, but distinguishing the highly similar microRNA sequences between these remains challenging. We report a five-strand four-way junction (5S-4WJ) electrochemical biosensor that combines universal reporter strands with target-specific probes for a modular, low-cost design. The system discriminates miR-146b from its isomiR (R + 2, +2 nt at 3' end) by tuning the probe length, introducing mismatches, and controlling the hybridization kinetics. This strategy yields sevenfold higher sensitivity for R + 2 while maintaining specificity at 10-50 nM. Compared to existing electrochemical biosensors, which struggle to or do not test targets with extra nts at either 5' or 3', the 5S-4WJ sensor enables precise isomiR detection, advancing nucleic acid diagnostics.
