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

purposeCurrent topical treatments using lidocaine (LD) for analgesia have limited applications due to their delayed analgesic actions, resulted from slow drug permeation through skin. The aim of this study is to fabricate a large size microneedle (MN) array patch containing LD, with fast onset of action, for the treatment of acute and chronic pain.

methodsThe MN patch was developed through photolithography and tested for its mechanical characteristics. In vitro and in vivo skin permeation, plasma pharmacokinetics, histology and skin irritation testing have also been performed for the MN patches.

resultsThe MN have a mechanical strength of 10-30 N and more than 90% of the microneedles on the patch penetrated skin. It was shown that LD permeated through skin within 5 min of patch application. Subsequently, the in vivo skin permeation study using a porcine model showed that LD administrated by the MN patch was able to achieve the therapeutic level locally within 10 min and sustained for 8 h. It shows most of the drug diffuses perpendicularly against skin, with little lateral diffusion. After skin permeation LD remains within skin and unquantifiable amount of LD was found in the plasma of the pigs. Minor skin irritations were observed after 6 h of microneedle contact. However, the skin irritations resolved within 1 day following the removal of MN patch.

conclusionThe large size MN patches showed fast onset and sustained delivery of LD through skin, potentially useful to increase the application scope of topical LD for pain management.
