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
purposeCentaurea lycopifolia Boiss. et Kotschy (Asteraceae) is traditionally used in folk medicine for wound healing. This study aimed to develop and pharmacologically evaluate a novel oral microemulsion containing C. lycopifolia extract, focusing on its analgesic and anti-inflammatory effects in rodent models.
methodsThe extract, obtained from aerial parts of the plant, was characterized by LC-MS/MS. A microemulsion formulation was developed for oral administration. Antinociceptive activity was evaluated via hot plate (HP) and tail flick (TF) tests to assess central and spinal effects, respectively. Anti-inflammatory activity was assessed using carrageenan-induced paw edema, quantified by plethysmometry and Randall-Selitto tests.
resultsLC-MS/MS analysis identified quinic acid, chlorogenic acid, and protocatechuic acid as major phytoconstituents. In both HP and TF tests, the C. lycopifolia microemulsion demonstrated significantly stronger antinociceptive effects than aspirin. Similarly, its anti-inflammatory activity was comparable to aspirin. These pharmacological effects are possibly associated with the synergistic actions of the phenolic acids present in the extract.
conclusionsThe C. lycopifolia-loaded microemulsion exhibited strong in vivo analgesic and anti-inflammatory activity, supporting its potential as a phytopharmaceutical candidate for inflammatory pain. The use of both central and peripheral pain models provided a robust pharmacodynamic basis for its therapeutic potential. Overall, these findings highlight the relevance of phenolic-rich phytochemicals in oral delivery systems for inflammation-related disorders.
