Antipneumococcal activity of grepafloxacin compared to that of other agents by time-kill methodology.
Article in Antimicrobial agents and chemotherapy, 1998. The graph could read no effect estimate from its abstract, so it casts no vote on the map. Cited by 4 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
Time-kill studies compared the activities of grepafloxacin with those of ciprofloxacin, levofloxacin, sparfloxacin, amoxicillin-clavulanate, and clarithromycin against 12 pneumococcal strains. Grepafloxacin was bactericidal after 24 h against all strains at a concentration of < or = 0.5 microg/ml, while sparfloxacin, levofloxacin, and ciprofloxacin were bactericidal at concentrations of < or = 1.0, < or = 2.0, and < or = 8.0 microg/ml, respectively. Amoxicillin-clavulanate and clarithromycin were bactericidal at 2x the MIC after 24 h against 12 of 12 strains and against all 8 macrolide-susceptible strains, respectively.
