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

Lactococcal conjugative plasmids are poorly characterized compared to those harbored by numerous other Gram-positive bacteria, despite their significance in dairy fermentations and starter culture development. Furthermore, the transcriptional landscape of these lactococcal conjugation systems and their regulation have not been studied in any detail. Lactococcal plasmids pNP40 and pUC11B possess two genetically distinct and prevalent conjugation systems. Here, we describe the detailed transcriptional analysis of the pNP40 and pUC11B conjugation-associated gene clusters, revealing three and five promoters, respectively, for which the corresponding transcriptional start sites were identified. Regulation of several of these promoters, and therefore conjugation, is shown to involve the individual or concerted activities of the corresponding relaxase and transcriptional repressor(s) encoded by each conjugative plasmid. This work highlights how the conjugative potential of these systems may be unlocked, with significant implications for the starter culture and food fermentation industry.
