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 study presents a Quality by Design (QbD) strategy combined with Design of Experiments (DoE) to develop hybrid polymer-lipid hot-melt extruded (HME) formulations aimed at improving the dissolution rate and palatability of ibuprofen (IBU), a Biopharmaceutics Classification System (BCS) Class II drug with poor aqueous solubility. A fractional factorial design was applied to evaluate the influence of Eudragit EPO and Gelucire 48/16 (GLC) ratios on the preparation of IBU-loaded extrudates. Physicochemical characterisation of the micronised extrudates, using differential scanning calorimetry (DSC) and X-ray powder diffraction (XRPD), confirmed the formation of amorphous solid dispersions (98.0-99.8%). The DoE analysis demonstrated that the EPO/GLC ratio significantly affected crystallinity, particle size distribution, and dissolution performance. The optimised hybrid polymer-lipid formulations exhibited immediate drug release (> 80%) within 45 min. Furthermore, in vivo evaluation indicated effective taste masking and improved palatability.
