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
High altitude hypoxia (HAH) involves the pathogenesis of ulcerative colitis (UC) and gastrointestinal erosions. However, the mechanism of effects of HAH in colitis remains controversial. This study reports the immunomodulation mediated by HAH to enhancing the severity of UC in the mice model. BALB/c mice were used to establish the UC model by dextran sulfate sodium (DSS) compared to wild type mice. Mice groups were exposed to hypoxic conditions in a hypobaric chamber with an altitude of 5000 m for 7 days. Then, Spleen, mesenteric lymph nodes and colon tissues were collected. The activity of UC, the infiltration of the immune cells, and the released cytokines were investigated. Results showed that the severity of DSS-induced UC significantly increased in mice exposed to HAH. The analysis of pathological changes showed increased weight loss and decreased colon length accompanied by diarrhea and bloody feces in the hypobaric hypoxia group. Interestingly, the levels of inflammatory cytokines IL-17, TNF-α, and IFN-γ in the spleen and mesenteric lymph node showed a significant increase within the colon of the hypobaric hypoxia group. The population of Th 1 and Th 17 cells in the spleen was significantly increased in mice exposed to hypobaric hypoxia compared NC group. Suggesting that high altitude hypoxia enhances colitis in mice through activating the increase of inflammatory Th1 and Th17 lymphocytes. In conclusion, this study revealed that hypobaric hypoxia directly increases the severity of UC in the mice model via increasing the activity of inflammatory CD4+ Th1 and Th 17 lymphocytes.
