Insulin-like growth factor-I (IGF-I) colocalizes with IGF-binding proteins (IGFBPs) in mouse and rat ovary.

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.
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
The cellular localization of insulin-like growth factor (IGF)-I mRNA, IGF-I peptide, and IGF-binding proteins (IGFBPs) was examined in mouse and rat ovaries through use ofin situ hybridization and immunohistochemical methods. IGF-I mRNA was found to be most abundant in granulosa cells, although lower levels were also detected in cells of the theca interna, stroma, and corpus luteum. In contrast, IGF-I immunoreactivity was undetectable or low in granulosa cells, weak and variable in oocytes, high in theca interna and the corpus luteum, and highest in the stroma. Antibodies directed against IGFBP-2, 3, and 5 yielded similar patterns of immunoreactivity to that observed for IGF-I peptide. The results indicate that IGF-I is synthesized in ovarian follicles, and that IGF-I of ovarian or systemic origin becomes localized to sites containing IGFBPs in the ovary.
