Causative Agents of Fungal Keratitis in Northeastern Iran: A 3-Year Tertiary Care Hospital Study.

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
Infectious keratitis is a significant ocular disease that, if left untreated, can lead to blindness. Fungi are among the causative agents that can result in severe symptoms. Keratitis infections are prevalent globally, with a higher incidence reported in tropical and subtropical regions. The current research focused on the molecular diagnosis of fungal keratitis and its prevalence over a 3-year period in northeastern Iran. The study involved the collection of 38 corneal scraping specimens from the Eye Specialized Hospital of Khatam in Mashhad, northeastern Iran. These specimens were cultured on Sabouraud dextrose agar, and the isolates were identified using DNA-based techniques. Among the patients studied (n = 38), 22 (58%) cases were caused by Aspergillus species (A. flavus, n = 17, A. fumigatus, n = 3; A. terreus, n = 1; A. tubingensis, n = 1), seven (18%) by Neocosmospora species (N. falciformis, n = 4; N. solani, n = 3), three (7%) by Candida albicans, two (5%) by Fusarium annulatum, and one case each (2%) by Penicillium chrysogenum, Cladosporium cladosporioides, and Cytospora sp. In addition, one case had a combined infection of A. flavus and P. glabrum. The results indicate a higher incidence of fungal keratitis in males, particularly in the age range of 40-60 years. Aspergillus sp., and specifically A. flavus, had the highest prevalence. Cladosporium cladosporioides is reported for the first time in this area as causal agent of keratitis. Additionally, this is the first report of keratitis likely caused by Cytospora species.
