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 established the distribution of amino acid alterations in quinolone resistance-determining regions (QRDRs) of Streptococcus pneumoniae isolates in Japan and described the correlation of these alterations with serotypes determined by multilocus sequencing typing. Among 141 S. pneumoniae isolates, five levofloxacin-resistant isolates harbored mutations in both gyrA and parC and/or parE and were clonally unrelated. Among 136 levofloxacin-susceptible isolates, one isolate (MIC = 2 mg/l) had a first-step parC mutation at Asp78. Twenty isolates had Lys137Asp in parC and Ile460Val in parE and contained nine serotypes and eight clonal complexes (CCs), including all eight Colombia(23F)-26 (CC138) isolates. Eighty-one isolates had Ile460Val in parE alone and contained 14 serotypes and 16 CCs, including 36 of 37 Netherlands(3)-31 (CC180) isolates and all 22 Taiwan(19F)-14 (CC271) isolates. In contrast, seven of ten Taiwan(23F)-15 (CC242) isolates were wild-type. Although each QRDR genotype contained various serotypes and CCs, prevalent clones were mostly associated with a single QRDR genotype.
