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
Among 180 clinical isolates of pneumococci, no strains were found to be resistant to levofloxacin (MIC, > or = 4 micrograms/ml) whereas 9% were resistant to ofloxacin and 7% were resistant to ciprofloxacin. Synergism was demonstrated by time-kill studies in nine of nine strains for the combination of levofloxacin and vancomycin and in six of nine strains for levofloxacin plus teicoplanin. The combinations of levofloxacin with rifampin or fusidic acid were indifferent. Resistant mutants could be selected using incremental concentrations of levofloxacin. For two of nine strains that were initially susceptible to levofloxacin, the MICs reached the resistance range (> or = 4 micrograms/ml). In contrast, ciprofloxacin and ofloxacin selected mutants from the susceptible to the resistant range more frequently (four of six and six of seven strains, respectively). These data argue for further study of levofloxacin against penicillin-resistant pneumococci.
