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

A model is presented for the translocation dynamics of the strand displacement DNA synthesis by DNA polymerases such as polymerase I family. (i) The model gives an explanation to the experimental results which showed that the rate of strand displacement DNA synthesis is nearly consistent with that of single stranded primer extension synthesis, although the two are expected to have substantial differences in their energetics. (ii) During strand displacement DNA synthesis, the pausing at the specific sequence is considered to be due to an affinity of the fingers subdomain for the specific sequence of dsDNA downstream of the single strand. The theoretical results on the sequence-dependent pausing dynamics such as the mean pausing lifetimes and the distribution of the pausing lifetime are consistent with the experimental data. Moreover, predicted results are presented for the binding affinity of the fingers subdomain for the specific sequence of dsDNA and the dependence of the mean sequence-dependent pausing lifetime on the external force acting on the polymerase.
