Evaluating the in vitro efficacy of gatifloxacin, levofloxacin and gentamicin against Acanthamoeba cysts.

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
purposeTo evaluate the in vitro efficacy of three commercial ophthalmic solutions (gatifloxacin, levofloxacin and gentamicin) against cysts of Acanthamoeba species.
designExperimental study
methodsAcanthamoeba cysts belonging to genotypes T3, T4 and T5 were incubated with three ophthalmic solutions for different periods of time; 1, 24, 48 and 72 h at 37 °C. After incubation, treated cysts were stained with trypan blue and counted to express the percent of growth inhibition. Additionally, the viability of treated cysts was assessed by culturing them in PYG medium at 30 °C for 72 h as well as on non-nutrient agar plates at 30 °C for 1 month.
resultsAcanthamoeba cysts of all genotypes were susceptible to gentamicin and gatifloxacin after exposure for 1 h and 24 h, respectively, and for levofloxacin, cysts of all genotypes were resistant to levofloxacin even after 72 h of incubation. Gentamicin and gatifloxacin showed statistically highly significant difference (P < 0.001), and levofloxacin showed statistically significant difference (P < 0.05) in comparison to non-treated control.
conclusionsGentamicin and gatifloxacin were highly effective against Acanthamoeba cysts. Although our results should be confirmed in animal models, this result will guide the choice of the appropriate ophthalmic drugs for early treatment of eye infection caused by Acanthamoeba spp.
