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
MHTP [2-methoxy-4-(7-methoxy-1,2,3,4-tetrahydroisoquinolin-1-yl) phenol], a synthetic isoquinolinic alkaloid, presented anti-inflammatory activity in several experimental models of acute inflammation as lipopolysaccharide (LPS)-induced acute lung injury and phlogistic agent-induced edema and presented low preclinical toxicity. The aim of this study was to determine the MHTP effect on ovalbumin (OVA)-induced pulmonary allergic inflammation. In other to realize this study, female BALFB/c mice were sensitized and challenged with OVA (OVA group) and treated with MHTP (MHTP group) by nasal instillation. Inflammatory, allergic, and immunomodulatory parameters such as migration of inflammatory cells to the lung tissue, pulmonary histological analysis, serum level of IgE-allergen specific, cytokine secretion, and lung T cell population characterization were analyzed and the data were considered statistically significant with p < 0.05. OVA-sensitized and OVA-challenged and MHTP (5.0 mg/kg)-treated mice presented reduction on total leukocyte migration into the bronchoalveolar lavage (BALF) dependent of lymphocyte and eosinophil migration (p < 0.001 and p < 0.01) as compared with the OVA group. Flow cytometric analysis showed that MHTP treatment decreased the percentage of granulocytes (p < 0.001) into the BALF and lung tissue histological analyzes demonstrated that the MHTP treatment decreased leukocyte migration and mucus production. In addition, treatment with MHTP decreased the number of CD3
