1 · What the graph read from it

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.

2 · The registry

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 novel metoprolol succinate tablet-in-tablet-in-tablet system was developed using hot-melt granulation combined with twin-screw continuous processing to provide an accurate 24-h sustained release. Tablet-in-tablet-in-tablet system was optimized using Quality by Design, considering key formulation and process parameters such as polymer composition, kneading temperature, screw speed, and feed rate to ensure reproducibility and scalability. The three-layer architecture was tailored to release the drug in a timed sequence, allowing the outer, middle, and core compartments to contribute to a gradual and predictable release profile that closely approached zero-order kinetics. Physicochemical characterization confirmed the stability of metoprolol succinate within the polymeric matrix. Additionally, in vivo studies in rats supported the sustained release behaviour, while accelerated stability testing indicated retention of formulation integrity and dissolution performance for three months. This work describes the development and evaluation of a scalable and robust platform for controlled-release oral dosage forms which could serve as a practical alternative to conventional single-layer or pellet-based systems.
