Rabbit Fungal Keratitis Model of Fusarium solani Tested Against Three Commercially Available Antifungal Drugs.
Article in Eye & contact lens, 2020. The graph could read no effect estimate from its abstract, so it casts no vote on the map. Cited by 8 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
objectivesThe purpose of this study was to develop a reproducible preclinical Fusarium solani keratitis model, which would allow comparative testing of currently available antifungals (NATACYN [Alcon, Fort Worth, TX], voriconazole 1%, and amphotericin B 0.1%) as well as efficacy testing of new antifungals for translation into clinical practice in the future.
methodsThe rabbit F. solani keratitis model was developed in New Zealand white rabbits using local and systemic immunosuppression. Infection was introduced by intrastromal injection of F. solani spores into one of the immunosuppressed rabbit eyes while the contralateral eye was a control. Progress of the infection was assessed by the clinical features, histopathology, and viable fungal counts. In this study, the efficacy of currently available antifungals (NATACYN [Alcon], voriconazole 1%, and amphotericin B 0.1%) was compared. Rabbits were randomly divided (n=4 in each group), and the respective antifungal was instilled topically 5 times/day for 7 days. Treatment effects were analyzed by evaluating the anterior segment with the help of slit-lamp, histopathological findings and viable fungal culture at the end of the experiment.
resultsWe report the development of a reproducible and progressive rabbit F. solani keratitis model as shown by the substantial viable fungal counts (3 log CFU), the presence of large patchy lesions and substantial hypopyon in the 12-day model correlated with specific histopathological analysis for fungus (extended F. solani hyphae from midcorneal stroma into the anterior chamber and traverse Descemet membrane with anterior chamber suppurative plaque). Voriconazole 1% and NATACYN revealed significant reduction of the fungal wound area (P=0.02 and 0.021), respectively, while amphotericin B 0.1% exhibited P value of 0.083 compared with their infected nontreated controls. Voriconazole 1% and amphotericin B 0.1% showed significant viable fungal count differences (P=0.004 and 0.01), respectively, whereas P value of NATACYN was 0.337 compared with control infected corneas.
conclusionThe reported rabbit fungal keratitis model can be used for screening new antifungals and evaluating currently available antifungals to facilitate better clinical outcomes. Voriconazole 1% showed the best efficacy among the three tested currently available antifungals by showing the significant differences in both wound size and viable fungal count comparisons in our F. solani rabbit keratitis model.
