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

The plastid genome is transcribed by two distinct RNA polymerases, the PEP encoded by the plastid genome and the NEP encoded in the nucleus. Initial models of plastid transcription held that the NEP is responsible for the transcription of housekeeping genes needed early in development, and that the PEP transcribes genes required for photosynthesis. Recently, this model was challenged by the discovery that all plastid genes are transcribed by NEP in PEP-deficient tobacco plastids, suggesting that mRNA turnover may have a strong role in previously observed transcription patterns. In this study, we provide evidence that the NEP enzyme level decreases as plastids mature. In contrast, production of mRNAs by NEP increases as plastids mature, yet their accumulations remain constant. These results suggest that as plastids mature NEP may become more active, and that mRNA turnover varies between transcripts synthesized by NEP and PEP.
