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

In mycobacteria, the glucose-based disaccharide trehalose cycles between the cytoplasm, where it is a stress protectant and carbon source, and the cell envelope, where it is released as a byproduct of outer mycomembrane glycan biosynthesis and turnover. Trehalose recycling via the LpqY-SugABC transporter promotes virulence, antibiotic recalcitrance, and efficient adaptation to nutrient deprivation. The source(s) of trehalose and the regulation of recycling under these and other stressors are unclear. A key technical gap in addressing these questions has been the inability to trace trehalose recycling in situ, directly from its site of liberation from the cell envelope. Here we describe a bifunctional chemical reporter that simultaneously marks mycomembrane biosynthesis and subsequent trehalose recycling with alkyne and azide groups. Using this probe, we discovered that the recycling efficiency for trehalose increases upon carbon starvation, concomitant with an increase in LpqY-SugABC expression. The ability of the bifunctional reporter to probe multiple, linked steps provides a more nuanced understanding of mycobacterial cell envelope metabolism and its plasticity under stress.
