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
introductionRepeated skin contact to detergents causes chronic irritant contact dermatitis (ICD) associated with itch sensation and eczema. However, the mechanisms of detergent-induced ICD are poorly understood. Here, we established a new murine model of detergent-induced ICD with H1-antihistamine-refractory itch.
methodsEar skin of wild-type and mast cell-deficient mice on the C57BL/6 genetic background was treated with a detergent, sodium dodecyl/lauryl sulfate (SDS), daily for approximately 2 weeks with or without administration of an H1-antihistamine, fexofenadine. Skin inflammation, barrier dysfunction, and itching were analyzed. Quantitative PCR for earlobe gene expression and flow cytometry analysis for draining lymph node cells were conducted.
resultsSDS treatment induced skin inflammation with ear swelling, increased transepidermal water loss, and hind-paw scratching behaviors in the wild-type and mast cell-deficient mice. The peak value of scratching bouts was retained for at least 48 h after the last SDS treatment. H1-antihistamine administration showed no or little reduction in the responses. SDS treatment upregulated gene expression for a Th2 cytokine IL-4 and Th17/Th22 cytokines, IL-17A, IL-17F, and IL-22, and increased cell numbers in draining lymph nodes of CD4+ T, CD8+ T, and γδT cells with enhanced expression of GATA3, RORγt, T-bet, or FOXP3 compared with untreated mice.
conclusionsThe present study showed that SDS treatment of ear skin in C57BL/6 mice induces mast cell-independent skin inflammation with H1-antihistamine-refractory itch and suggested a possible Th cytokine- and/or lymphocyte-mediated regulation of the model. The model would be useful for elucidation of mechanisms for inflammation with H1-antihistamine-refractory itch in detergent-induced ICD.
