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

Deletion analysis and alanine-scanning based on a homology-based interaction model were used to identify determinants of oligomerization in the transcriptional regulator CynR, a member of the LysR-type transcriptional regulator (LTTR) family. Deletion analysis confirmed that the putative regulatory domain of CynR was essential for driving the oligomerization of lambda repressor-CynR fusion proteins. The interaction surface of a different LTTR and OxyR was mapped onto a multiple sequence alignment of the LTTR family. This mapping identified putative contacts in the CynR regulatory domain dimer interface, which were targeted for alanine-scanning mutagenesis. Oligomerization was assayed by the ability of mutant lambda repressor-CynR fusions to assemble in E. coli revealing interesting similarities and differences between OxyR and CynR.
