Ruvbl1 silencing affects reproduction of the corn planthopper, Peregrinus maidis.
Article in PloS one, 2024. 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
Ruvbl1 (also known as TIP49, Pontin) encodes an ATPase of the AAA+ protein superfamily involved in several cellular functions, including chromatin remodeling, control of transcription, and cellular development (motility, growth, and proliferation). While its role has been well established in model organisms including vertebrates and invertebrates (e.g. mice, Xenopus and Drosophila), putative functions of Ruvbl1 in non-model insect pests have not been addressed. To exploit Ruvbl1 as a potential target gene for applications in insect control, we used an in-vivo RNA interference (RNAi) approach to evaluate the effect of Ruvbl1 silencing on the physiology of the corn planthopper, Peregrinus maidis. Silencing of P. maidis Ruvbl1 (PmRuvbl1) was correlated with visible morphology changes in female individuals with significant increases in body mass observed at 8 and 12 days after double strand RNA (dsRNA) injection. Ovary function was significantly affected in adult females with PmRuvbl1 silenced, with no mature oocytes observed at 8 and 12 days after gene silencing. Whereas no significant difference in egg laying was observed 4 days after dsRNA injection, significantly fewer eggs were laid in plants at 8 and 12 days after dsRNA treatment. Furthermore, dramatic reductions in egg hatching were observed at all time points after PmRuvbl1 silencing, compared to dsGFP-injected controls. These results extend Ruvbl1 functions as a putative regulator of P. maidis reproduction and demonstrate the potential of Ruvbl1 to be further exploited as a target for developing new technologies (e.g. RNA interference, CRISPR-mediated control) for insect control.
