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
A better functional and site-specific drug delivery system for ophthalmic disease is necessary for the treatment of glaucoma. The present study aimed to design a brinzolamide (BRZ)-loaded cubosomal solid lipid nano-vesicular system (Cube-SLNV) that accomplished advanced statistical tools. Another objective was to overcome the problem of burst release associated with Glyceryl monooleate (GMO) Cube-SLNV by incorporating Gelucire 43/01 (GC43/01). The emulsification method was used to synthesize BRZ Cube-SLNV. The Plackett-Burman design (PBD) was utilized to screen the critical material (CMAs) and process attributes (CPPs). The optimization of the Cube-SLNV was accomplished through Box-Behnken design (BBD). Multivariate tools were applied to estimate the correlation between screened CMAs and critical quality attributes (CQAs). The Cube-SLNV was characterized by size, its size distribution, stability, thermal behavior, chemical interactions, BRZ release, entrapment efficiency, pH, sterility testing, and ex vivo irritation study. GMO and GC43/01 were chosen as solid lipids, whereas Poloxamer 407 (PLX) was a stabilizer for Cube-SLNV in preliminary trials. PBD-the Pareto chart suggested the significant influence of the amount of GMO, GC43/01, and PLX on the performance of Cube-SLNV, so chosen as CMAs for further optimization. BBD identified a crucial relationship between chosen CMAs and CQAs - Cube-SLNV size, poly-dispersibility index (PDI), and BRZ release. The optimized Cube-SLNV size was determined to be 101.2 nm, with a zeta potential of - 34.6 mV, a PDI of 0.253, and more than 90% entrapment efficiency. Cube-SLNV can release more than 90% BRZ within 8 h. DSC and FTIR confirmed the formation of Cube-SLNV-loaded BRZ. HATCAM study revealed that the formulation has no irritancy. The controlled release behavior from optimized BRZ with higher entrapment efficiency was observed. Cube-SLNV was developed with the amalgamation of PBD for screening and BBD for correlating CMAs and CQAs. This novel delivery system is a revitalized formulation that promises to give a potential molecule a new lease of life.
