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

Aims: Oestrogen drives long-bone development through various oestrogen receptors. G-protein-coupled oestrogen receptor-1 (GPER-1), a membrane oestrogen receptor, mediates longitudinal bone growth during early puberty; however, the underlying mechanisms remain unclear. Therefore, this study elucidated the mechanisms underlying GPER-1-mediated bone growth. Methods: A GPER-1 agonist (G1), GPER-1 antagonist (G15), and chondrocyte-specific GPER-1 knockout experiment ( Results: G1 treatment-induced GPER-1 activation increased tibial growth plate thickness, proliferative zone thickness, and chondrocyte proliferation in mice. The hypertrophic zone thickness and type X collagen-stained area decreased in four-week-old G1-treated mice compared with the control group. GPER-1 activation increased the PTHrP/Ihh ratio in the growth plates of four- and eight-week-old mice. In contrast, blocking or deleting GPER-1 decreased the proliferative zones of the growth plate, proliferative chondrocytes, and PTHrP/Ihh. Additionally, the hyperopic zones of the growth plates increased with GPER-1 deficiency. In vitro micromass-3D cultured chondrocyte studies confirmed that G1 treatment increased proliferation, decreased hypertrophy, and increased PTHrP/Ihh protein levels. Conclusion: This study demonstrates that GPER-1 maintains proliferation but suppresses chondrocyte hypertrophy in growth plates by upregulating PTHrP/Ihh during early puberty in male and female mice. Our findings suggest that GPER-1 may serve as a potential target for therapeutic modulation of linear bone growth during puberty.
