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 growth of Clostridium tyrobutyricum in developing cheese leads to spoilage and cheese blowing. Bacteriophages or their specific lytic enzymes may provide a biological control method for eliminating such undesirable organisms without affecting other microflora. We isolated the virulent bacteriophage phiCTP1 belonging to the Siphoviridae and have shown that it is effective in causing lysis of sensitive strains. The double-stranded DNA genome of phiCTP1 is 59,199 bp, and sequence analysis indicated that it has 86 open reading frames. orf29 was identified as the gene coding for the phage endolysin responsible for cell wall degradation prior to virion release. We cloned and expressed the ctp1l gene in E. coli and demonstrated that the partially purified protein induced lysis of C. tyrobutyricum cells and reduced viable counts both in buffer and in milk. The endolysin was inactive against a range of clostridial species but did show lysis of Clostridium sporogenes, another potential spoilage organism. Removal of the C-terminal portion of the endolysin completely abolished lytic activity.
