1 · What the graph read from it

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.

2 · The registry

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

Germ granules are biomolecular condensates that promote germ cell totipotency in animals. In C. elegans, MEG-3 and MEG-4 function redundantly to assemble germ granules in germline blastomeres. Here, we show that meg-3/4 mutant animals exhibit defects in RNA interference (RNAi) that are transgenerationally disconnected from the meg-3/4 genotype. Similar non-Mendelian inheritance is associated with other mutations disrupting germ granule formation, indicating that loss of germ granules is the likely cause of the observed disconnects between genotype and phenotype. meg-3/4 animals produce aberrant siRNAs that are propagated for ≅10 generations in wild-type descendants of meg-3/4 ancestors. Aberrant siRNAs inappropriately and heritably silence germline-expressed genes including the RNAi gene sid-1, suggesting that transgenerational silencing of sid-1 underlies inherited defects in RNAi. We conclude that one function of germ granules is to organize RNA-based epigenetic inheritance pathways and that germ granule loss has consequences that persist for many generations.
