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

Bone is a dynamic organ constantly undergoing remodeling with both bone formation and resorption. Bone formation is mediated by osteoblasts originating from the differentiation of bone marrow (BM) mesenchymal stem and progenitor cells (BM-MSPCs). However, how bone cells communicate with BM-MSPCs to coordinate bone formation remains largely elusive. Here, we unveil a key role of osteocyte connexin 43 (Cx43) hemichannels in regulating the lineage commitment of BM-MSPCs. Two transgenic mouse models expressing dominant negative Cx43 mutants in osteocytes were used: R76W (inhibiting gap junctions) and Δ130 to 136 (inhibiting both hemichannels and gap junctions). BM-MSPCs from Δ130 to 136 mice showed enhanced adipogenic differentiation and reduced osteogenic potential, leading to increased BM adipocytes. Flow cytometry and single-cell RNA sequencing revealed shifts in BM-MSPC subsets, less osteogenic-biased MSPCs, and more adipogenic-biased MSPCs in Δ130 to 136 mice. Conversely, R76W, with more functional hemichannels, exhibited effects similar to WT mice or even greater opposite effects than Δ130 to 136 mice. Prostaglandin E
