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

In yeast mitochondria, transcription initiation requires assembly of mitochondrial RNA polymerase and transcription initiation factor MTF1 at the DNA promoter initiation site. This protocol describes the purification of the component proteins and assembly of partially melted and fully melted initiation complex states. Both states co-exist in equilibrium in the same sample as seen by cryoelectron microscopy (cryo-EM) and allow elucidation of MTF1's structural roles in controlling the transition into elongation. We further outline how analysis of the complex by light scattering, thermal shift assay, and ultrafiltration assay exhibits reproducible results. For complete details on the use and execution of this protocol, please refer to De Wijngaert et al. (2021).
