Period homolog LIN-42 regulates miRNA transcription to impact developmental timing.
Article in Worm. The graph could read no effect estimate from its abstract, so it casts no vote on the map. Cited by 11 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
Two recent studies by Van Wynsberghe et al. and Perales et al. in the nematode C. elegans have demonstrated a new function of the Period protein homolog LIN-42 in negatively regulating microRNA (miRNA) biogenesis at the transcriptional level. LIN-42 is a complex gene with 4 isoforms and multiple functions including the regulation of molting, developmental timing and entry into dauer. These recent studies uncover an additional function of LIN-42 as a negative regulator of miRNA transcription. Approximately 95% of miRNAs present in eggs and 33% of miRNAs present in L4 stage worms were upregulated in lin-42 mutant worms relative to wild type (WT) worms, suggesting that LIN-42 globally regulates miRNA biogenesis. Expression from both a let-7 miRNA and a lin-4 miRNA transcriptional reporter were enhanced in the absence of lin-42. Additionally, chromatin immunoprecipitation followed by high throughput sequencing (ChIP-seq) of late larval stage worms showed that LIN-42 bound the let-7 promoter, suggesting that LIN-42 affects mature miRNA levels by inhibiting their transcription. In addition to miRNAs, LIN-42 also predominantly bound to the promoters of many diverse protein-coding genes. These findings support the action of LIN-42 at multiple points within the heterochronic and other regulatory pathways to impact a multitude of functions including developmental timing.
