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 (IGF)-l and IGF-ll peptides as well as their mRNAs are produced in many organs, including the pituitary. Although IGFl and IGFII peptides are localized in endocrine cells of the anterior pituitary, IGF-l mRNA can be detected throughout the adenohypophysis, and IGF-ll mRNA is abundant in intermediate and neural lobes. It is well-established that both circulating and intrinsic IGF-l are negative regulators of pituitary GH production. Other functions of intrinsic IGFs in normal and tumorous pituitary are just emerging. IGF-l may play a role in the stimulation of PRL synthesis and mediation of proliferative effects of estrogen on lactotroph. Compared with IGF-l, the function of IGE-Il has not been clarified so far. The growth-promoting actions of IGFs are mediated by IGF-l receptor. The role of local and circulating IGFBPs in pituitary are not yet documented. IGFBPs in other tissues have inhibitory and stimulatory effects on IGFs, and can act independently from the IGFs as well. IGFs have been reported to promote cell proliferation in many tumors. However, the extent to which IGFs contribute to pituitary tumor development and growth remains obscure.
