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
Objectives: "Quality by Design" (QbD) is a novel approach to product development that involves understanding the product and process, as well as the relationship between critical quality attributes (CQA) and critical process parameters (CPP). This study aimed to optimize the gabapentin-loaded solid lipid nanoparticle formulation (GP-SLN) using a QbD approach and evaluate in vitro and ex vivo performance. Materials and Methods: The GP-SLN formulation was created using the microemulsion method by combining Gelucire 48/16, Tween 80, and Plurol Oleique CC 497. The Box-Behnken experimental design was adopted to investigate the effects of independent factors on dependent factors. The GP-SLN formulation was assessed based on particle size and distribution, zeta potential, morphology, entrapment efficiency, release kinetics, permeation parameters, stability, and nasal toxicity. Results: The nanoparticles had a cubical shape with a particle size of 185.3±45.6 nm, a zeta potential of -24±3.53 mV, and an entrapment efficiency of 82.57±4.02%. The particle size and zeta potential of the GP-SLNs remained consistent for 3 months and followed Weibull kinetics with a significantly higher Conclusion: The current study reports the successful development of a GP-SLN formulation using QbD. A sustained release of GP was achieved and its nasal permeability was increased. Solid lipid nanoparticles with optimum particle size and high entrapment efficiency may offer a promising approach for the intranasal delivery of drugs.
