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
backgroundUterine receptivity for the implantation is a complicated process, that ovarian factors (hormonal), endometrium and embryo simultaneously are involved in this phenomenon. A successful implantation needs appropriate development of the endometrium. Furthermore, embryo must be capable of reacting with the endometrium and producing suitable adhesion molecules. This study aimed to examine one of endometrial maturation indices in mice before implantation, i.e., proliferation of stromal cells. MATERIALS AND
methodsA total of 40 adult female mice were divided into four groups: Control, gonadotropin, gonadotropin + progesterone, and gonadotropin + sildenafil citrate. The three experimental groups were first injected 7.5 IU of human chorionic gonadotropin (HCG) and then 7.5 IU of human menopausal gonadotropin (HMG). Then, every two female mice were placed in a cage with a male mouse for mating. Two groups were injected 1 mg of progesterone and 3 mg/kg of sildenafil citrate at intervals of 24, 48, and 72 h after injection of HMG. After 96 h, all the mice were killed, and their uterine samples subjected to tissue passage and prepared for analysis. Immunohistochemical method, Ki-67, and stromal mitotic cell count were used in this study.
resultsOur observations in all groups showed changes in the luminal epithelium. ANOVA analysis Ki-67-positive stromal cells among all groups were not statistically significant.
conclusionThe results showed that administration of HMG and HCG following that of progesterone and sildenafil citrate could change the indices of endometrial maturation, and they were not involved in the phase immediately before implantation in stromal mitotic index.
