The maximum possible amount of drug in rapidly separating microneedles.
Article in Drug delivery and translational research, 2019. The graph could read no effect estimate from its abstract, so it casts no vote on the map. Cited by 7 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
There is an increasing concern on the drug loading capacity of microneedles (MNs) to meet higher drug dosage requirement. The present study describes the fabrication of modified rapidly separating polyvinyl alcohol (PVA)-based MNs (RS-P-MNs) with high drug loading using a mechanical agitation process. The drugs encapsulated within the PVA polymer gel by mechanical agitation served as an encapsulating agent for drugs that provide a high drug loading capacity and also release of drugs in a controlled manner. The various parameters such as microscopic analysis, atomic force microscopy (AFM), drug loading, drug delivery efficiency, mechanical test, skin penetration ability, and in vitro and in vivo analyses indicate the great potential of the RS-P-MNs. The maximum drug loading capacity of RS-P-MNs was measured to be approximately 900 ng per microneedle, which was almost a hundred times than the traditional drug encapsulating mode. The in vitro and in vivo results suggested that the controlled release of drugs is due to the encapsulating mode (mechanical agitation) of drugs. The prepared RS-P-MNs with high drug loading in this study provided a gentle and controlled release of drugs instead of the robust release of drugs from traditional MNs. Graphical abstract.
