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

It is known that insulin resistance and type 2 diabetes mellitus are associated with increased fractures and that brown adipose tissue (BAT) counteracts many if not all of the symptoms associated with type 2 diabetes. By the use of FoxC2(AD)(+/Tg) mice, a well-established model for induction of BAT, or beige fat, we present data extending the beneficial action of beige fat to also include a positive effect on bone. FoxC2(AD)(+/Tg) mice are lean and insulin-sensitive and have high bone mass due to increased bone formation associated with high bone turnover. Inducible BAT is linked to activation of endosteal osteoblasts whereas osteocytes have decreased expression of the Sost transcript encoding sclerostin and elevated expression of Rankl. Conditioned media (CM) collected from forkhead box c2 (FOXC2)-induced beige adipocytes activated the osteoblast phenotype and increased levels of phospho-AKT and β-catenin in recipient cells. In osteocytes, the same media decreased Sost expression. Immunodepletion of CM with antibodies against wingless related MMTV integration site 10b (WNT10b) and insulin-like growth factor binding protein 2 (IGFBP2) resulted in the loss of pro-osteoblastic activity, and the loss of increase in the levels of phospho-AKT and β-catenin. Conversely, CM derived from cells overexpressing IGFBP2 or WNT10b restored osteoblastic activity in recipient cells. In conclusion, beige fat secretes endocrine/paracrine activity that is beneficial for the skeleton.
