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
Shin'iseihaito (Xinyiqingfeitang) is a formula of traditional Japanese Kampo medicine and traditional Chinese medicine (TCM) and for chronic sinusitis. However, the precise action mechanism has been unknown. We examined the effect of shin'iseihaito extract (SSHT) on murine allergic rhinitis model using ovalbumin (OVA). We decocted the mixture of 9 crude drugs in water to prepare SSHT. SSHT (20 times amount of human dose) was orally administered to mice treated with OVA. After mice were sacrificed on day 28, immunoglobulin (Ig) E, interleukin (IL)-4, IL-13, interferon (IFN)-γ, and thymic stromal lymphopoietin (TSLP) levels in nasal lavage fluid samples were measured by enzyme-linked immunosorbent assay (ELISA). The pathological tissue sections from the nasal epithelial mucosa were histopathologically investigated by optical and scanning electron microscopies. We also investigated the effects of modified SSHTs prepared by removing one crude drug from shin'iseihaito to clarify the active ingredients. SSHT suppressed IgE, IL-4, IL-13, and TSLP levels, while increased the IFN-γ levels in OVA-induced allergic mice. Sensitization with OVA resulted in an increase in eosinophilia and goblet cells in murine nasal cavity tissue in comparison with those in untreated group, however, those were significantly reduced by the treatment with SSHT. The extracts of 8 crude drug's mixtures except for the removal of Gypsum fibrosum (GF) from shin'iseihaito counteracted on the suppressive effects of SSHT on IgE, IL-4, IL-13, and TSLP levels in nasal lavage fluid. Our result demonstrated that SSHT may contribute to inhibit the exacerbation of OVA-induced murine allergic rhinitis by regulating cytokines, and the components except for GF contributed anti-allergic effect of shin'iseihaito.
