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

objectiveSpinal fusion surgery is a common treatment modality for various pathologic conditions of the spine. The bone morphogenetic protein 2 (BMP2) analogue L51P acts as a general inhibitor of BMP antagonists, whereas it shows a weak affinity for BMP type I receptor. It is suggested that L51P applied in bone disorders might prevent side effects of highly concentrated BMP dosage applications in the order of milligrams. The objective of this study was to investigate the effects of L51P and BMP2 on intervertebral disc cells (IVDCs), i.e. on nucleus pulposus cells, on annulus fibrosus cells (AFCs), and on cartilaginous endplate cells (CEPCs), respectively, in 3-dimensional (3D) culture.

methodsLow-passage primary IVDCs were cultured in 3D alginate bead culture and exposed to 100-ng/mL BMP2 and/or L51P for 21 days. Here, we analyzed glycosaminoglycan (GAG) and DNA content and further performed gene expression analysis for major matrix genes.

resultsAFCs and cartilaginous CEPCs stimulated with each 100-ng/mL L51P and BMP2, showed a significant upregulation in GAG (AFCs: p = 0.00347 and CEPCs: p = 0.0115) and DNA production (AFCs: p = 0.0182 and CEPCs: p = 0.0179) compared to control.

conclusionThese results allow first insights into the behavior of IVDCs upon L51P stimulation.
