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

M102AD is the new designation for a Streptococcus mutans phage described in 1993 as phage M102. This change was necessitated by the genome analysis of another S. mutans phage named M102, which revealed differences from the genome sequence reported here. Additional host range analyses confirmed that S. mutans phage M102AD infects only a few serotype c strains. Phage M102AD adsorbed very slowly to its host, and it cannot adsorb to serotype e and f strains of S. mutans. M102AD adsorption was blocked by c-specific antiserum. Phage M102AD also adsorbed equally well to heat-treated and trypsin-treated cells, suggesting carbohydrate receptors. Saliva and polysaccharide production did not inhibit plaque formation. The genome of this siphophage consisted of a linear, double-stranded, 30,664-bp DNA molecule, with a GC content of 39.6%. Analysis of the genome extremities indicated the presence of a 3'-overhang cos site that was 11 nucleotides long. Bioinformatic analyses identified 40 open reading frames, all in the same orientation. No lysogeny-related genes were found, indicating that phage M102AD is strictly virulent. No obvious virulence factor gene candidates were found. Twelve proteins were identified in the virion structure by mass spectrometry. Comparative genomic analysis revealed a close relationship between S. mutans phages M102AD and M102 as well as with Streptococcus thermophilus phages. This study also highlights the importance of conducting research with biological materials obtained from recognized microbial collections.
