Determination of Gentamicin C-subtypes in Inner Ear Perilymph Using Liquid Chromatography with Fluorescence Detection.
Article in Journal of pharmaceutical and biomedical analysis, 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
Gentamicin is a broad-spectrum aminoglycoside used frequently to treat gram-positive and gram-negative bacterial infections. In this study, a new, simple, fast, and sensitive isocratic reversed-phase high performance liquid chromatography (RP-HPLC) method was developed and validated for the detection and quantification of fluorescent OPA-ethanethiol derivatized gentamicin in very small biological sample volumes. To our knowledge, there is no report of the use of ethanethiol for the derivatization of gentamicin with OPA, and the simultaneous determination of the four major C-subtypes of gentamicin using OPA-derivatives. Optimum chromatographic conditions were achieved on a C
