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

objectiveTo examine the ultrastructural characteristics of extracellular matrix and mature collagen fibrils in uterine leiomyomas and compare them with those in adjacent normal myometrium.

designAnalysis of paired leiomyoma-myometrium in surgical specimens.

settingResearch center and tertiary care center. SUBJECT(S): Women undergoing medically indicated hysterectomy for symptomatic uterine leiomyomas. INTERVENTION(S): None. MAIN OUTCOME MEASURE(S): Appearance and spatial orientation of the collagen fibrils in leiomyomas compared with myometrium. RESULT(S): Observation of specimens at x 12,500 magnification indicated that collagen fibrils were more abundant, loosely packed, and arrayed in a nonparallel manner in leiomyomas compared with myometrium. Random areas were examined at x 6,500 to x 64,000 magnification and revealed collagen fibrils of equal diameter in both leiomyomas and myometrium. However, an ordered and regular barbed appearance was present in collagen fibrils from myometrium but was lacking in leiomyomas. CONCLUSION(S): Leiomyomas contain an abnormal collagen fibril structure and orientation, which suggests that the well-regulated fibril formation in myometrium is altered in leiomyomas. Alterations in collagen genes may play a role in the pathogenesis of leiomyomas.
