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

Microneedle arrays have emerged as an alternative method for transdermal drug delivery. Although micromolding using a centrifugation method is widely used to prepare microneedles in laboratory, few researchers were focused on manufacturing processes capable of facile scale-up. A novel female mold was initially designed in this study, namely double-penetration female mold (DPFM) with the pinpoints covered by waterproof breather membrane which was beneficial to reduce the influence of gas resistance and solution viscosity. In addition, DPFM-based positive-pressure microperfusion technique (PPPT) was proposed for the scale-up fabrication of dissolving microneedle arrays (DMNA). In this method, polymer solution and base solution were poured into the DPFM by pressure difference, followed by drying and demolding. The results of optimal microscopy and SEM revealed that the obtained microneedles were uniformly distributed conical-shaped needles. The skin penetration test showed that DMNA prepared using PPPT were able to penetrate the rat skin with a high penetration rate. To realize the transition of microneedles fabrication from laboratory to industry, an automatic equipment was further designed in this study. Different from micromolding method using centrifugation, the equipment based on PPPT and DPFM has superiorities in the scale-up fabrication of microneedles in a highly effective, controllable, and scalable way.
