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

MAIN

conclusionMaize Dek570-1 affects the expression and function of organellar genes by performing cytidines-to-uridines RNA editing at specific sites of mitochondrial and chloroplast transcripts, thereby regulating seed and plant development. Cytidines-to-uridines (C-to-U) RNA editing at specific sites of mitochondrial and plastid transcripts is crucial for the expression and function of organellar genes, which requires PPR proteins. Here, we report the map-based cloning and characterization of Defective Kernel 570-1 (Dek570-1), which encodes a PPR-DYW protein and is an allele of Emp17. However, compared to the empty pericarp and embryonic lethality of emp17 (W22 background), dek570-1 (Zheng58 background) can produce small but viable seeds despite reducing the size of embryo and endosperm. dek570-1 plants are short and yellowed, but they can reproduce offspring. In mitochondria, loss-of-function of Dek570-1 abolishes the C-to-U editing at nad2-677 and ccmF
