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

Designed self-assembled DNA crystals consist of rigid DNA motifs that are held together by cohesive sticky-ended interactions. A prominent application of such systems is that they might be able to act as macromolecular hosts for macromolecular guests, thereby alleviating the crystallization problem of structural biology. We have recently demonstrated that it is indeed possible to design and construct such crystals and to determine their structures by X-ray diffraction procedures. To act as useful hosts that organize biological macromolecules for crystallographic purposes, maximizing the resolution of the crystals will maximize the utility of the approach. The structures reported so far have diffracted only to about 4 Å, so we have examined two factors that might have impact on the resolution. We find no difference in the resolution whether the DNA is synthetic or PCR-generated. However, we find that the presence of a phosphate on the 5'-end of the strands improves the resolution of the crystals markedly.
