Solid-state properties and antibiotic potency of levofloxacin - dicarboxylate salts prepared by the green method.
Article in Heliyon, 2024. The graph could read no effect estimate from its abstract, so it casts no vote on the map. Cited by 3 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
This research dealt with the green methods to react levofloxacin (LF) with dicarboxylate acids: oxalic acid (OX), succinic acid (SA), malonic acid (MN), and maleic acid (MA) and investigated its impact on the LF's stability, solubility, and antimicrobial potency, which never been reported before. Solvent-dropped grinding (SDG) using ethanol 95 % was used to prepare the organic antibiotic salts, reducing the solvent usage significantly compared to the conventional solvent evaporation method, supported with solid-state characterization using electrothermal, differential scanning calorimetry and powder X-ray diffractometry. Next, Fourier Transform Infrared Spectroscopy and Nuclear Magnetic Resonance (1H-NMR) confirmed and determined the interaction structure between LF and the acids. Afterward, the benefits of the LF-dicarboxylate salts were investigated, including stability, solubility, and antibiotic potency. The results demonstrated that the SDG could produce LF-OX hydrate, LF-SA hydrate, and anhydrous LF-MN in a (1:1) molar ratio, with a diffractogram never yet explained. Meanwhile, the LF-MA (1:1) salt solid-state structure was identical to the reported one. Notably, these LF-dicarboxylates showed better solubility, stability, and potency than LF alone, suggesting potential for further dosage formulations.
