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

Drosophila germ granules are enriched with mRNAs critical for development. Within them, mRNAs cluster through intermolecular interactions that may involve base pairing. Here we apply in silico, in vitro and in vivo approaches to examine the type and prevalence of these interactions. We show that RNA clustering can occur without extended sequence complementarity (stretches of six or more continuous complementary bases) and that mRNAs display similar level of foldedness within germ granules as outside. Our simulations predict that clustering is driven by scattered, surface-exposed bases, enabling intermolecular base pairing. Notably, engineered germ granule mRNAs containing exposed GC-rich complementary sequences within stem loops located in the 3' untranslated region promote intermolecular interactions. However, these mRNAs are also expressed at lower levels, leading to developmental defects. Although germ granule mRNAs contain numerous GC-rich complementary sequences, RNA folding renders them inaccessible for intermolecular base pairing. We propose that RNA folding restricts intermolecular base pairing to maintain proper mRNA function within germ granules.
