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

CS1-LS4 and CS2-LS12 are ultra-high affinity and orthogonal RNA-protein pairs that were identified by PD-SELEX (Phage Display coupled with Systematic Evolution of Ligands by EXponential enrichment). To investigate the molecular basis of the lab-coevolved RNA-RBP pairs, we determined the structures of the CS1-LS4 and CS2-LS12 complexes and the LS12 homodimer in an RNA-free state by X-ray crystallography. The structural analyses revealed that the lab-coevolved RNA-RBPs have acquired unique molecular recognition mechanisms, whereas the overall structures of the RNP complexes were similar to the typical kink-turn RNA-L7Ae complex. The orthogonal RNA-RBP pairs were applied to construct high-performance cell-free riboswitches that regulate translation in response to LS4 or LS12. In addition, by using the orthogonal protein-responsive switches, we generated an AND logic gate that outputs staphylococcal γ-hemolysin in cell-free system and carried out hemolysis assay and calcein leakage assay using rabbit red blood cells and artificial cells, respectively.
