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
Intravaginal infection of mice with Chlamydia muridarum has been used for investigating the mechanisms of Chlamydia trachomatis-induced pathogenicity and immune responses. In the current study, the mouse model was used to evaluate the impact of interleukin-27 (IL-27) and its receptor signaling on the susceptibility of the female genital tract to chlamydial infection. Mice deficient in IL-27 developed significantly shortened courses of chlamydial infection in the female genital tract. The titers of live Chlamydia recovered from the genital tract of IL-27-deficient mice declined significantly by day 7 following intravaginal inoculation. These observations suggest that IL-27 may promote chlamydial infection in the female mouse genital tract. This conclusion was validated using IL-27 receptor (R)-deficient mice. Further, the reduction in chlamydial burden corelated with the increase in gamma interferon (IFN-γ) and IL-17 in the genital tract tissues of the IL-27R-deificent mice. However, depletion of IFN-γ but not IL-17 from the IL-27R-deificent mice significantly increased the chlamydial burden, indicating that IL-27 may mainly suppress IFN-γ-mediated immunity for promoting chlamydial infection. Finally, knockout of IL-27R from T cells alone was sufficient for significantly shortening the infectious shedding courses of Chlamydia in the mouse genital tract. The above-described results have demonstrated that Chlamydia can activate IL-27R signaling in Th1-like cells for promoting its infection in the female genital tract, suggesting that attenuating IL-27 signaling in T cells may be used for enhancing genital tract immunity against chlamydial infection.
