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

Insulin-like growth factor type I (IGF-I) is an important promoter in the tumorigenesis of several extracranial and intracranial neoplasms. In astrocytic-cell tumors, the role of autocrine and paracrine IGF-I expression in enhancing tumoral progression is well established. However, the influence of systemic IGF-I levels on the clinical behavior of astrocytic neoplasms remains an open subject of research. We report the case of a 28-year-old man who presented simultaneously with acromegaly and an anaplastic astrocytoma, which had rapidly progressed from a low-grade astrocytoma. The coexistence of systemic IGF-I hypersecretion with a quick progression in the histopathological grade of the astrocytoma raises the compelling question of whether the clinical behavior of the astrocytic tumor was influenced by the acromegalic status. The role of IGF-I signaling in the pathogenesis of astrocytic-cell tumors and the experience with therapeutic strategies addressing this pathway in astrocytomas are also discussed.
