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

The evolution of new enzymatic functions is constrained and guided by the architecture of an organism's metabolic and regulatory networks and environmental constraints. Here, we identify a kinase that has evolved from pyruvate phosphate dikinase. Using biochemical and systems-level analyses, we show that this enzyme, encoded by rv1127c in Mycobacterium tuberculosis (Mtb), has diverged from its ancestral role in central carbon metabolism to function as a histidine kinase in pathogenic mycobacteria and related species. We designate this enzyme Virulence Associated DiKinase (VadK), reflecting its ability to autophosphorylate and its role in virulence. VadK is essential for the utilization of carbon sources critical for survival within the host and to cause tuberculosis (TB) in murine models. Furthermore, VadK interacts with enzymes of the methylcitrate cycle, and
