Analysis of Vibrio seventh pandemic island II and novel genomic islands in relation to attachment sequences among a wide variety of Vibrio cholerae strains.

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
Vibrio cholerae O1 El Tor, the pathogen responsible for the current cholera pandemic, became pathogenic by acquiring virulent factors including Vibrio seventh pandemic islands (VSP)-I and -II. Diversity of VSP-II is well recognized; however, studies addressing attachment sequence left (attL) sequences of VSP-II are few. In this report, a wide variety of V. cholerae strains were analyzed for the structure and distribution of VSP-II in relation to their attachment sequences. Of 188 V. cholerae strains analyzed, 81% (153/188) strains carried VSP-II; of these, typical VSP-II, and a short variant was found in 36% (55/153), and 63% (96/153), respectively. A novel VSP-II was found in two V. cholerae non-O1/non-O139 strains. In addition to the typical 14-bp attL, six new attL-like sequences were identified. The 14-bp attL was associated with VSP-II in 91% (139/153), whereas the remaining six types were found in 9.2% (14/153) of V. cholerae strains. Of note, six distinct types of the attL-like sequence were found in the seventh pandemic wave 1 strains; however, only one or two types were found in the wave 2 or 3 strains. Interestingly, 86% (24/28) of V. cholerae seventh pandemic strains harboring a 13-bp attL-like sequence were devoid of VSP-II. Six novel genomic islands using two unique insertion sites to those of VSP-II were identified in 11 V. cholerae strains in this study. Four of those shared similar gene clusters with VSP-II, except integrase gene.
