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

Chains of inorganic polyphosphate (poly-P) with hundreds of P(i) residues linked by phosphoanhydride bonds, as in ATP, are found in every bacterial, fungal, plant, and animal cell, in which they perform various functions. In the spore-forming Bacillus cereus, we have identified three principal enzymes and genes involved in the metabolism of poly-P, namely, (i) poly-P kinase (PPK), which synthesizes poly-P reversibly from ATP, (ii) exopolyphosphatase (PPX), which hydrolyzes poly-P to P(i), and (iii) poly-P/AMP phosphotransferase (PAP), which uses poly-P as a donor to convert AMP to ADP, reversibly. In the null mutant of ppk, poly-P levels are reduced to <5% of the WT; in the ppx mutant, the PPK activity is elevated 10-fold, and the accumulation of poly-P is elevated approximately 1,000-fold. All of the null mutants of ppk, ppx, and pap showed defects in motility and biofilm formation, but sporulation efficiency was impaired only in the ppx mutant. These enzymes and genes in B. cereus are nearly identical to those in the very closely related pathogen Bacillus anthracis, and, thus, they may provide attractive targets for the treatment of anthrax.
