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

Weak organic acids have been used for centuries to preserve foods, but only recently has the possible mechanism for bacterial growth inhibition been investigated. Although the lowering of internal pH was favored as the cause of growth inhibition, the emphasis has shifted to the anion and its specificity. There are a number of applications of weak organic acids to foods and in the food industry be they pre- or postharvest, However, there is concern that the ability of foodborne pathogens to adapt to these acids may allow longer survival in these commodities and also to better survive transit through the gastric acid barrier of the stomach. Genomic and proteomic approaches have been applied to the identification of genes and proteins that may allow prokaryotes to cope with organic acid stress. These technologies in combination with genetic approaches may provide better identification of genes essential for survival to organic acids. These acids may have other roles: they can induce phenotypic antibiotic resistance, and the high concentrations of these acids in the colon may signal a relationship to diet, colonic microflora, and human health.
