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 expanded backbone chemistries of xeno-nucleic acids (XNAs) hold significant promise for emerging areas of synthetic biology and nanomaterials, but metal-mediated XNA interactions remain largely unexplored. Here, we use a combination of circular dichroism spectroscopy and mass spectrometry to show that XNAs can form Ag+-mediated duplex structures resembling their DNA counterparts. XNAs with a range of different backbone compositions are found to stabilize photoluminescent silver nanoclusters with spectral properties that can be tuned based on their respective backbone chemistry. The resistance of silver nanoclusters to nuclease digestion is also compared for DNA and XNAs. These results show that XNA backbone chemistry provides a new tool beyond nucleobase sequence for controlling and expanding the properties of nucleic acid-stabilized silver nanoclusters and metal-mediated DNA duplexes.
