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
Patients frequently experience physical, mental, and even financial distress because of acute or chronic skin wounds. In severe situations, scarring on the skin can be quite noticeable, cause persistent discomfort, restrict joint motion, or be mentally taxing. Hair-follicle-associated pluripotent (HAP) stem cells were discovered by our laboratory, in the bulge area of the hair follicle and can differentiate to neurons, glia, beating cardiomyocytes, keratinocytes and nascent vessels. In the present study, HAP stem cell sheets were formed by culturing the upper part of hair follicles and implanting into mice with skin ulcers. The HAP stem cell sheets contained keratinocytes, endothelial cells and neurons. Autologous HAP stem cell sheet implantation to the dorsal wound in C57BL/6J mice significantly accelerated wound closure compared with non-implanted control mice. HAP-stem-cell sheets expressing green fluorescent protein (GFP) implanted into nude mice differentiated into keratinocytes in the epidermis, and neurons and endothelial cells in the dermis. The thicknesses of the epidermis and dermis and M2 macrophage and myofibroblast infiltration into the wound were significantly decreased in HAP-stem cell-implanted mice compared with non-implanted control mice. Expression levels of TGF-β1, COL1A2 and COL3A1 mRNA in the wound were significantly decreased in HAP stem cell-implanted mice compared with non-implanted control mice. These results suggest that implanting HAP stem cell sheets accelerates cutaneous wound closure and suppresses scar formation. The HAP stem cells used in the present study thus have potential as a future clinical strategy for accelerating wound healing.
