The human genome encodes a multitude of novel miRNAs.
Article in Nucleic acids research, 2025. The graph could read no effect estimate from its abstract, so it casts no vote on the map. Cited by 8 papers.
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
Human cells generate a vast complexity of noncoding RNAs, the "RNA dark matter," which includes a vast small RNA (sRNA) transcriptome. The biogenesis, biological relevance, and mechanisms of action of most of these transcripts remain unknown, and they are widely assumed to represent degradation products. Here, we aimed to functionally characterize human sRNA transcriptome by attempting to answer the following question-can a significant number of novel sRNAs correspond to novel members of known classes, specifically, microRNAs (miRNAs)? By developing and validating a miRNA discovery pipeline, we show that at least 2726 novel canonical miRNAs, majority of which represent novel miRNA families, exist in just one human cell line compared to just 1914 known miRNA loci. Moreover, potentially tens of thousands of miRNAs remain to be discovered. Strikingly, many novel miRNAs map to exons of protein-coding genes emphasizing a complex and interleaved architecture of the genome. The existence of so many novel members of a functional class of sRNAs suggest that the human sRNA transcriptome harbors a multitude of novel regulatory molecules. Overall, these results suggest that we are at the very beginning of understanding the true functional complexity of the sRNA component of the "RNA dark matter."
