Sustainable chromatographic assays of a novel antifungal combination for keratomycosis.
Article in BMC chemistry, 2026. The graph could read no effect estimate from its abstract, so it casts no vote on the map. Not yet cited in PubMed.
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
Keratomycosis, a sight-threatening fungal infection of the cornea, can be more effectively treated with a novel combination of Natamycin (NAT, 5%) and Fluconazole (FLC, 0.2%) than with NAT alone. To support the development of this therapy, new sustainable, eco-friendly, and sensitive analytical methods were developed for the simultaneous quantification of both drugs in pharmaceutical formulations. Two techniques were successfully employed. The first was a Reversed-Phase High-Performance Liquid Chromatography (RP-HPLC) method using an isocratic mobile phase of methanol and water (70:30%v/v) at a 1 mL/min flow rate. Detection was accomplished with both diode array (DAD) and fluorescence (FLD) detectors. The second technique was a Capillary Zone Electrophoresis (CZE) method utilizing a capillary (56 cm effective length, 50 μm internal diameter) at ambient temperature. Samples were injected hydrodynamically at 50 mbar pressure. The environmental sustainability and practical applicability of these methods were rigorously evaluated using modern assessment tools: the Greenness, Whiteness, and Blueness approaches. Furthermore, their innovative character was formally quantified using a novel metric, the Violet Innovation Grade Index (VIGI).
