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

X-ray crystallography of biologically important RNA molecules has been hampered by technical challenges, including finding heavy-atom derivatives to obtain high-quality experimental phase information. Existing techniques have drawbacks, limiting the rate at which important new structures are solved. To address this, we have developed a reliable means to localize heavy atoms specifically to virtually any RNA. By solving the crystal structures of thirteen variants of the G*U wobble pair cation binding motif, we have identified a version that when inserted into an RNA helix introduces a high-occupancy cation binding site suitable for phasing. This "directed soaking" strategy can be integrated fully into existing RNA crystallography methods, potentially increasing the rate at which important structures are solved and facilitating routine solving of structures using Cu-Kalpha radiation. This method already has been used to solve several crystal structures.
