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
Pro-opiomelanocortin (POMC) is a large precursor protein of and β-endorphin. POMC expressed in keratinocytes regulates various pathophysiological responses, such as pruritus in atopic dermatitis. Interleukin (IL)-31 is a T helper 2 (Th2)-derived cytokine that functions as a pruritogen, stimulating the sensory neurons in the skin. However, the regulatory mechanism underlying IL-31-induced POMC expression in keratinocytes remains largely unknown. Herein, using a 5'-serial deletion and site-specific mutation constructs of the regulatory region of POMC, we demonstrated that a putative EGR1-binding sequence (EBS) motif in POMC is required for its upregulation by IL-31 in HaCaT keratinocytes. Notably, EGR-1 directly interacted with the EBS motif in POMC. The ectopic expression of EGR-1 stimulated the POMC promoter activity, whereas the knockdown of EGR-1 expression by RNA interference reduced IL-31-induced POMC expression. Furthermore, we observed that three major mitogen-activated protein kinases, ERK, JNK, and p38 kinase, mediated IL-31-induced EGR-1 expression. In summary, our results suggest that EGR-1 trans-activates POMC in response to IL-31 stimulation in HaCaT keratinocytes.
