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
We have shown previously that downregulation of intercaruncular stromal integrin alphavbeta3 in bovine endometrium on day 16 of the estrous cycle coincided with the antibody recognition of estrogen receptors (ER) in the luminal epithelium. In pregnancy, these changes were not observed. Our hypothesis was that on day 16 of the estrous cycle, estrogen from the dominant follicle causes a reduction in integrin alphavbeta3 and affects ERalpha in the luminal epithelium. The pregnancy recognition protein, interferon-tau (IFN-tau), may prevent downregulation of integrin alphavbeta3 and suppress ERalpha expression in the luminal epithelium. On days 14 to 16, heifers received uterine infusions of the anti-estrogen ICI 182, 780, estradiol 17beta, IFN-tau or the saline control. On day 16, reproductive tracts were collected for analysis of integrin alphavbeta3 and ERalpha. Estrogen receptor alpha immunoreactivity was largely restricted to the luminal epithelium in control animals. Using anti-ERalpha recognizing the amino terminus, estrogen-treated animals showed reactivity in the stroma, shallow and deep glands and myometrium as is typical of estrus, whereas ICI 182, 870 treated heifers showed little or no reactivity. In contrast, carboxyl terminus-directed antibodies showed a widespread distribution of ERalpha with reactivity detected in the uterine epithelium, stroma and myometrium of both estrogen and ICI 182, 780 treated animals. Heifers treated with IFN-tau had low ERalpha reactivity overall. Control and IFN-tau treated heifers had lower intercaruncular stromal expression of integrin alphavbeta3 in comparison to estrogen and ICI 182, 780 treatments. Overall, the results suggest that on day 16 of the estrous cycle, estrogen effects on integrin alphavbeta3 are indirect and do not directly involve ERalpha in the luminal epithelium. During pregnancy, interferon-tau may block ERalpha in the luminal epithelium but likely does not rescue integrin alphavbeta3 expression.
