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
Restoring hyaluronic acid (HA) content is important for maintaining the function of photo-aged skin. This study aimed to evaluate the passive delivery into skin of HA nanoparticles formed by the polyion complex method. Nanoparticles were prepared by mixing and stirring anionic HA with a cationic polymer, protamine, at the charge ratio 55:45. The permeation of fluorescently-labelled HA nanoparticles (HANP) or free HA through hairless mouse skin was characterized in vitro. HANP or free HA was applied to ultraviolet (UV)-irradiated mice in vivo, and their transepidermal water loss (TEWL) was measured after 4 days. HA that had been delivered into skin was separated and characterized by molecular sieve chromatography. HANP were able to deliver HA into the dermis both in vitro and in vivo, whereas free HA penetrated no further than the stratum corneum. Following HANP application, HA within the skin was present in the form of free HA rather than nanoparticles. When applied in vivo, HANP significantly reduced the TEWL caused by UV irradiation. Thus, although free HA does not penetrate into the skin by passive diffusion, HA can be effectively delivered by nanoparticles. HA is then released from the nanoparticles and can contribute to barrier recovery following UV irradiation.
