Genetic classification and distinguishing of Staphylococcus species based on different partial gap, 16S rRNA, hsp60, rpoB, sodA, and tuf gene sequences.
Article in Journal of clinical microbiology, 2008. The graph could read no effect estimate from its abstract, so it casts no vote on the map. Cited by 81 papers.
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 analysis of 16S rRNA gene sequences has been the technique generally used to study the evolution and taxonomy of staphylococci. However, the results of this method do not correspond to the results of polyphasic taxonomy, and the related species cannot always be distinguished from each other. Thus, new phylogenetic markers for Staphylococcus spp. are needed. We partially sequenced the gap gene (approximately 931 bp), which encodes the glyceraldehyde-3-phosphate dehydrogenase, for 27 Staphylococcus species. The partial sequences had 24.3 to 96% interspecies homology and were useful in the identification of staphylococcal species (F. Layer, B. Ghebremedhin, W. König, and B. König, J. Microbiol. Methods 70:542-549, 2007). The DNA sequence similarities of the partial staphylococcal gap sequences were found to be lower than those of 16S rRNA (approximately 97%), rpoB (approximately 86%), hsp60 (approximately 82%), and sodA (approximately 78%). Phylogenetically derived trees revealed four statistically supported groups: S. hyicus/S. intermedius, S. sciuri, S. haemolyticus/S. simulans, and S. aureus/epidermidis. The branching of S. auricularis, S. cohnii subsp. cohnii, and the heterogeneous S. saprophyticus group, comprising S. saprophyticus subsp. saprophyticus and S. equorum subsp. equorum, was not reliable. Thus, the phylogenetic analysis based on the gap gene sequences revealed similarities between the dendrograms based on other gene sequences (e.g., the S. hyicus/S. intermedius and S. sciuri groups) as well as differences, e.g., the grouping of S. arlettae and S. kloosii in the gap-based tree. From our results, we propose the partial sequencing of the gap gene as an alternative molecular tool for the taxonomical analysis of Staphylococcus species and for decreasing the possibility of misidentification.
