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

Salmonellae often have the ability to express two different flagellar antigen specificities (phase 1 and phase 2). At the cell level, only one flagellar phase is expressed at a time. Two genes, fliC, encoding phase-1 flagellin, and fljB, encoding phase-2 flagellin, are alternatively expressed. Flagellin genes from 264 serovars of Salmonella enterica were amplified by two phase-specific PCR systems. Amplification products were subjected to restriction fragment length polymorphism (RFLP) analysis by using endonucleases HhaI and HphI. RFLP with HhaI and HphI yielded 64 and 42 different restriction profiles, respectively, among 329 flagellin genes coding for 26 antigens. The phase-1 gene showed 46 patterns with HhaI and 30 patterns with HphI. The phase-2 gene showed 23 patterns with HhaI and 17 patterns with HphI. When the data from both enzymes were combined, 116 patterns were obtained: 74 for fliC, 47 for fljB, and 5 shared by both genes. Of these combined patterns, 80% were specifically associated with one flagellar antigen and 20% were associated with more than one antigen. Each flagellar antigen was divided into 2 to 18 different combined patterns. In the sample of strains used, determination of the phase-1 and phase-2 flagellin gene RFLP, added to the knowledge of the O antigen, allowed identification of all diphasic serovars. Overall, the diversity uncovered by flagellin gene RFLP did not precisely match that evidenced by flagellar agglutination.
