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

Blastocrithidia nonstop is a protist with a highly unusual nuclear genetic code, in which all three standard stop codons are reassigned to encode amino acids, with UAA also serving as a sole termination codon. In this study, we demonstrate that this parasitic flagellate is amenable to genetic manipulation, enabling gene ablation and protein tagging. Using preassembled Cas9 ribonucleoprotein complexes, we successfully disrupted and tagged the non-essential gene encoding catalase. These advances establish this single-celled eukaryote as a model organism for investigating the malleability and evolution of the genetic code in eukaryotes.
