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

Accurate hybridization is dependent on the ratio between sequence-specific and unspecific binding. Dissociation of unspecifically bound, while maintaining specifically hybridized, nucleic acids are key steps to obtain a well-defined complex. We have developed a new method, temperature-assisted, cyclic hybridization (TACH), which increases cognate binding at the expense of unspecific hybridization. The method was used for optimizing binding of peptide nucleic acid (PNA) to supercoiled plasmids and has several advantages over previous methods: (1) it reduces the required amount of bis-PNA by three- to fourfold; (2) it results in less unspecific binding; (3) it extends cooperative hybridization, from 3 bp to 5 bp between two adjacent binding sites; and (4) it decreases the aggregation of bis-PNA. This method might be extended to other forms of hybridizations including the use of additional nucleic acids analogs, such as locked nucleic acid (LNA) and, also, to other areas where PNAs are used such as fluorescence in situ hybridization (FISH), microarrays, or in vivo plasmid delivery.
