Microneedle Array Patch (MAP) Consisting of Crosslinked Hyaluronic Acid Nanoparticles for Processability and Sustained Release.
Article in Pharmaceutical research, 2020. The graph could read no effect estimate from its abstract, so it casts no vote on the map. Cited by 8 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
aimsCrosslinked hyaluronic acid (X-linked HA) is not suitable for making microneedles because of the low fluidity of X-linked HA hydrogel. Microneedles were fabricated using X-linked HA nanoparticles (X-linked HA-NPs) to utilize the sustained drug delivery capability of X-linked HA-NPs and to obtain the processability advantages of X-linked HA.
methodThe puncture performance of a microneedle array patch (MAP) made of crosslinked hyaluronic acid nanoparticles (X-linked HA-NP-MAP) was evaluated by insertion in vitro into porcine skin. After a predetermined attachment time, the remaining height of the X-linked HA-NP-MAP was measured to determine the dissolution rate. X-linked HA-NP-MAP and free HA-MAP containing Rhodamine B isothiocyanate-dextran were administered into the back skin of mice, and the relative fluorescent intensity in the back skin was measured over time.
resultsThe puncture performance of the X-linked HA-NP-MAP was over 90%. The diameter of redispersed X-linked HA-NPs was same as that of the premolded X-linked HA-NPs. The dissolution rate was not different from that of free HA-MAP. In an in vivo experiment, X-linked HA-NP-MAP was administered into the mouse's back skin successfully and the relative fluorescent intensity of X-linked HA-NP-MAP lasted longer than that of HA-MAP.
conclusionX-linked HA-NPs provide the biocompatibility, the processability of micromolding, sustained drug release, successful penetration into the skin, and relatively short insertion time for full disintegration of NPs in the skin. X-linked HA-NP-MAP can be used for various applications that require several days of sustained drug release.
