Influence of Plasdone
Article in AAPS PharmSciTech, 2021. The graph could read no effect estimate from its abstract, so it casts no vote on the map. Cited by 9 papers.
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
In a formulation, traces of peroxides in copovidone can impact the stability of drug substances that are prone to oxidation. The present study aimed to investigate the impact of peroxides in novel Plasdone™ S630 Ultra and compare it with regular Plasdone™ S630 on the oxidative degradation of quetiapine fumarate amorphous solid dispersions prepared via hot-melt extrusion technique. The miscibility of copovidones with drug was determined using the Hansen solubility parameter, and the results indicated a miscible drug-polymer system. Melt viscosity as a function of temperature was determined for the drug-polymer physical mixture to identify the suitable hot-melt extrusion processing temperature. The binary drug and polymer (30:70 weight ratio) amorphous solid dispersions were prepared at a processing temperature of 160°C. Differential scanning calorimetry and Fourier transform infrared spectroscopy studies of amorphous solid dispersions revealed the formation of a single-phase amorphous system with intermolecular hydrogen bonding between the drug and polymer. The milled extrudates were compressed into tablets by using extragranular components and evaluated for tabletability. Stability studies of the milled extrudates and tablet formulations were performed to monitor the oxidative degradation impurity (N-oxide). The N-oxide impurity levels in the quetiapine fumarate - Plasdone™ S630 Ultra milled extrudates and tablet formulations were reduced by 2- and 3-folds, respectively, compared to those in quetiapine fumarate - Plasdone™ S630. The reduced oxidative degradation and improved hot-melt extrusion processability of Plasdone™ S630 Ultra make it a better choice for oxidation-labile drugs over Plasdone™ S630 copovidone.
