Evolutionary origin of a monophasic Salmonella serovar, 9,12:l,v:-, revealed by IS200 profiles and restriction fragment polymorphisms of the fljB gene.

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.
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 emergence in several countries of the monophasic serogroup D1 serovar Salmonella 9,12:l,v:- provided the opportunity to study its evolutionary origin. According to current models, such a variant serovar could have arisen by horizontal transfer of a new flagellar gene to a preexisting monophasic Salmonella strain or, alternatively, by the loss of the phase 2 flagellar gene of an originally biphasic Salmonella strain. Five known serovars of Salmonella, S. panama, S. kapemba, S. goettingen, S. zaiman, and S. mendoza, could have been possible ancestors of the new variant. The profiles of the insertion element IS200, which has been shown to provide phylogenetic markers for serogroup D1 salmonellae, were analyzed in relation to the restriction fragment length polymorphisms of the phase 2 flagellar gene. Together they provide unequivocal evidence that Salmonella 9,12:l,v:- arose from a strain of S. goettingen. Analysis of the flj operon of the variant indicated that loss of phase 2 flagellar antigen expression occurred through deletion of the hin gene and adjacent DNA, thereby blocking the phase 2 flagellar gene in the off position.
