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
Purpose: To investigate the effects of C-type natriuretic peptide (CNP) on human granulosa cell growth and elucidate its regulatory mechanisms. Methods: A human non-luteinizing granulosa cell line (HGrC) developed from small antral follicles was used to assess the impact of CNP on cell proliferation and estrogen synthesis. cGMP production via the guanylate cyclase domain of the CNP receptor, natriuretic peptide receptor 2 (NPR2), was confirmed. The regulation of CNP encoding natriuretic peptide C (NPPC) and NPR2 by estradiol and oocyte-derived factors (ODFs) was examined. Results: Besides detecting both NPPC and NPR2, CNP increased cellular proliferation. The specific action of CNP on cell proliferation was confirmed using siRNA transfection. CNP stimulated cGMP production, whereas a guanylate-cyclase inhibitor suppressed CNP-induced cell proliferation. Estradiol production was elevated by CNP treatment, accompanied by increased expression of estrogen synthetic enzymes. Furthermore, CNP upregulated NPR2 expression in cooperation with estradiol and ODFs, while estradiol increased NPPC expression. Conclusion: This study demonstrates CNP stimulation of human granulosa cell growth and suggests potential cross-talk between these cells and oocytes. Further research on the simultaneous administration of CNP and estradiol may offer a promising approach for promoting early-stage follicle development in infertility treatments for patients with poor ovarian reserve.
