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
backgroundDry skin is a universal skin concern that is often accompanied by itching, but moisturizers have not completely solved this issue. We found that the combination of a moisturizer (lotion) and an ultra-thin film of fine fiber (FF) that we developed improved dry skin early, but the biological mechanism within the skin remained unclear. MATERIALS AND
methodsEight (Study 1) and seven (Study 2) subjects used a lotion with and without the FF film on their lower legs. In addition to measurement of visual skin dryness scores and conductance, proteomic analysis of stratum corneum (SC) samples at baseline and 14 days after treatment in Study 1 and immunohistochemical staining of skin biopsy samples 3 or 5 days after treatment in Study 2 were performed.
resultsSkin dryness scores and conductance improved more when the lotion was used with the FF film than with the lotion alone. The protein expression level of suprabasin, which is related to epidermal differentiation and barrier function, increased within a few days near the granular layer, as well as in the SC after 14 days. Proteomic analysis using SC samples showed that the FF film treatment with lotion decreased annexin A2, a dry skin marker, whereas it increased retroviral-like aspartic protease 1, which is related to skin water content, more than lotion alone.
conclusionThe present findings suggest that lotion with the FF film initiates restoration of epidermal homeostasis, leading to early improvement of dry skin.
