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

Although staphylococci are identified by phenotypic analysis in many clinical laboratories, these results are often incorrect because of phenotypic variation. Genetic analysis is necessary for definitive species identification. In the present study, we developed a simple multiplex-PCR (M-PCR) for species identification of human-associated staphylococci, which were as follows: Staphylococcus aureus, S. capitis, S. caprae, S. epidermidis, S. haemolyticus, S. hominis, S. lugdunensis, S. saprophyticus, and S. warneri. This method was designed on the basis of nucleotide sequences of the thermonuclease (nuc) genes that were universally conserved in staphylococci except the S. sciuri group and showed moderate sequence diversity. In order to validate this assay, 361 staphylococcal strains were studied, which had been identified at the species levels by sequence analysis of the hsp60 genes. In consequence, M-PCR demonstrated a sensitivity of 100% and a specificity of 100%. By virtue of simplicity and accuracy, this method will be useful in clinical research.
