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
Proliferation and migration of keratinocytes are vital processes for the successful epithelization specifically after wounding. MiR-221 has been identified to play a potential role in promoting wound regeneration by inducing blood vessel formation. However, little is known about the role of miR-221 in the keratinocyte proliferation and migration during wound healing. An in vivo mice wound-healing model was generated; the expression levels of miR-221 were assessed by qRT-PCR and fluorescence in situ hybridization. Initially, we found that miR-221 was upregulated in the proliferative phase of wound healing. Further, in an in vivo wound-healing mice model, targeted delivery of miR-221 mimics accelerated wound healing. Contrastingly, inhibition of miR-221 delayed healing. Additionally, we observed that overexpression of miR-221 promoted cell proliferation and migration, while inhibition of miR-221 had the opposite effects. Moreover, we identified SOCS7 as a direct target of miR-221 in keratinocytes and overexpression of SOCS7 reversed the effects of miR-221 in HaCaT keratinocytes. Finally, we identified that YB-1 regulates the expression of miR-221 in HaCaT keratinocytes. Overall, our experiments suggest that miR-221 is regulated by YB-1 in HaCaT keratinocytes and acts on SOCS7, thereby playing an important role in HaCaT keratinocyte proliferation and migration during wound healing.
