1 · What the graph read from it

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.

2 · The registry

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

This study aims to examine the expression of p53, p16, and murine double minute 2 (MDM2) protein in normal endometrium and endometriosis, in order to discuss the role of p53, p16, and MDM2 protein and apoptosis in the pathogenesis and development of endometriosis, and provide a theoretical basis for clinical diagnosis and treatment.The immunohistochemical streptavidin-biotin peroxidase method was used to detect the expression of p53, p16, and MDM2 in tissue samples obtained from 30 women with pathologically confirmed ovarian endometriosis and 29 women with pathologically confirmed normal endometrium. The relationship between p53, p16, and MDM2 expression and apoptosis was analyzed.In normal endometrium, the positive rate of p53 in the secretory phase was higher than that in the proliferative phase (P < .05). Furthermore, the positive rate of p53 in normal endometrium was higher than that in ovarian endometriosis (P < .05). There was a significant difference between normal endometrium and ovarian endometriosis.The positive rate of p16 in normal endometrium was higher than that in ovarian endometriosis (P < .05). Furthermore, there was a significant difference between normal endometrium and ovarian endometriosis. The positive rate of MDM2 in normal endometrium was lower than that in ovarian endometriosis (P < .05).In ovarian endometriosis, the expression of p53 and p16 was positively correlated with each other (r = 0.611, P < .01). However, the expression of p53 and MDM2 was negatively correlated with each other (r = -0.541, P < .01). Furthermore, the expression of p16 and MDM2 might not be relevant in the endometriosis (r = 0.404, P > .05).As important apoptosis regulatory genes, p53, p16, and MDM2 might be involved in the pathogenesis and development of endometriosis.
