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

We have used multilocus sequence typing (MLST) and serotyping to build a phylogenetic framework for pneumococcal disease isolates in Scotland that provides a snapshot of the relationships between capsular type and genotype. The results show that while the MLST type correlates with the serotype, isolates within a serotype can belong to a number of individual clonal complexes or sequence types (STs). We also show that isolates of the same ST can express different capsular polysaccharides, i.e., display capsular switching, and that this phenomenon is observed both for capsular types commonly isolated from patients with invasive disease and for serogroups less commonly isolated from patients with invasive disease but which may commonly be carried asymptomatically in the human nasopharynx.
