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

Mitochondria carry their own genetic material and gene-expression machinery, including ribosomes, which are responsible for synthesizing polypeptides that form essential components of the complexes involved in oxidative phosphorylation (or ATP generation) for the eukaryotic cell. Mitochondrial ribosomes (mitoribosomes) are quite divergent from cytoplasmic ribosomes in both composition and structure even as their main functional cores, such as the mRNA decoding and peptidyl transferase sites, are highly conserved. Remarkable progress has been made recently towards understanding the structure of mitoribosomes, by obtaining high-resolution cryo-electron microscopic (cryo-EM) maps. These studies confirm previous structural findings that had revealed that a significant reduction in size of ribosomal RNAs has caused topological changes in some of the functionally relevant regions, including the transfer RNA (tRNA)-binding sites and the nascent polypeptide-exit tunnel, within the structure of the mammalian mitoribosome. In addition, these studies provide unprecedented detailed views of the molecular architecture of those regions. In this review, we summarize the current state of knowledge of the structure of the mammalian mitoribosome and describe the molecular environment of its tRNA-exit region.
