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

To investigate the possible involvement of collagen in the characteristic features of human leiomyoma, type I, III and IV collagen expression was determined at the protein level in normal myometrium and leiomyoma tissues throughout the menstrual cycle. The tissues were obtained from 40 pre-menopausal women (29-53 years of age) at various stages of the menstrual cycle who were undergoing abdominal hysterectomy for symptomatic uterine leiomyoma. Immunohistochemical staining was performed with specific monoclonal antibodies against type I, III and IV collagen in the leiomyoma and the myometrial tissues. Immunohistochemical analysis revealed that type I collagen expression was increased in the leiomyoma tissues at the protein level as compared to that in the normal myometrium tissues throughout the menstrual cycle. These results suggest that increased expression of type I collagen plays a key role in the pathogenesis of uterine leiomyoma.
